I need to see what the next action is. Let me check the action choices.

gameMiMo Minimal's library is shuffled

thinkingMiMo Minimal

I need to select one card to put on the bottom of my library. This is likely a mulligan decision - I have 7 cards and need to bottom one. Looking at my hand: - **Archon of Cruelty** (6BB) - 6/6 flier with death trigger, very expensive - **Emperor of Bones** (1B) - 2/2 with graveyard exile and adapt, decent - **Faithless Looting** (R) - Draw 2 discard 2, good card advantage - **Polluted Delta** - Land, can fetch Island/Swamp - **Psychic Frog** (UB) - 1/2 that draws on damage, discard for counters, graveyard exile for flying - **Raucous Theater** - Land that enters tapped, surveil 1 when enters - **Scalding Tarn** - Land, can fetch Island/Mountain I need to bottom one card. The best choice is likely **Archon of Cruelty** - it's extremely expensive at 8 mana and not playable early. I want to keep the lands for mana, Faithless Looting for card advantage, Psychic Frog for early pressure, and Emperor of Bones as a solid two-drop.

Now I need to confirm if I want to keep this hand or mulligan further. Let me check the action.

gameMiMo Minimal puts a card from hand to the bottom of their library

thinkingMiMo Minimal

I'm being asked if I want to mulligan down to 5 cards. Looking at my current hand after bottoming Archon of Cruelty: - **Emperor of Bones** (1B) - 2/2 with graveyard exile and adapt - **Faithless Looting** (R) - Draw 2 discard 2 - **Polluted Delta** - Fetch land for Island/Swamp - **Psychic Frog** (UB) - 1/2 with card draw on damage, discard for counters - **Raucous Theater** - ETB tapped land, surveil 1 - **Scalding Tarn** - Fetch land for Island/Mountain This is actually a decent hand. I have: - 3 lands (2 fetches, 1 tapped land) - enough to play most spells - Faithless Looting to dig for more cards - Two good creatures (Emperor of Bones and Psychic Frog) - Good mana fixing with the fetches This hand should be keepable. Mulliganing down to 5 would put me at a disadvantage. I should keep this hand.

I'm in my first turn's main phase. I can play a land. Looking at my options: 1. **Polluted Delta** - Can fetch Swamp or Island 2. **Raucous Theater** - ETB tapped, surveil 1 when enters 3. **Scalding Tarn** - Can fetch Island or Mountain I need to consider my mana requirements. I have: - Emperor of Bones (1B) - needs black - Psychic Frog (UB) - needs blue and black - Faithless Looting (R) - needs red I have fetch lands that can get blue or black, and Raucous Theater can make red or black but enters tapped. The best play is likely **Polluted Delta** to fetch a Swamp (for black mana) since I have two black spells and only one red spell. Raucous Theater would come in tapped and not give me mana this turn, which is slower. Let me play Polluted Delta first.

Now I need to choose what to fetch with Polluted Delta. It can search for an Island or Swamp.

Playing Polluted Delta instead of Scalding Tarn means no red mana available this turn, missing the opportunity to cast Faithless Looting on turn 1. Faithless Looting is the ideal turn 1 play for this deck, fueling graveyard synergies with Emperor of Bones and Psychic Frog.

Analysis

Action taken: Played Polluted Delta, which can only fetch Island or Swamp (no red source).

Better line: Play Scalding Tarn, fetch a Mountain (or a dual that produces red), then cast Faithless Looting turn 1 to dig and fill the graveyard.

minor blunder

Cracking Polluted Delta during their own postcombat main phase when they can't cast anything this turn anyway.

Cracking Polluted Delta during their own postcombat main phase when they can't cast anything this turn anyway. There's no benefit to fetching now versus waiting until the opponent's end step, and cracking it now gives away information about their colors/deck unnecessarily.

Analysis

Action taken: Activated Polluted Delta during own postcombat main phase on turn 1.

Better line: Pass the turn and crack Polluted Delta at the end of the opponent's turn to preserve information and maintain flexibility on which land to fetch.

I can choose from various Islands and Swamps. Looking at the options: - Blood Crypt (Swamp Mountain) - can make black and red - Island - Steam Vents (Island Mountain) - can make blue and red - Swamp - Undercity Sewers (two copies) - need to check what they are - Watery Grave (two copies) - need to check what they are I need to check the oracle text for the unknown cards to make the best choice. Let me check some of them.

Now I can see the options: 1. **Blood Crypt** - Swamp Mountain (can make black and red) 2. **Island** - Basic Island 3. **Steam Vents** - Island Mountain (can make blue and red) 4. **Swamp** - Basic Swamp 5. **Undercity Sewers** - Island Swamp, enters tapped, surveil 1 6. **Watery Grave** - Island Swamp, can pay 2 life to enter untapped I need to consider my spells: - Emperor of Bones (1B) - needs black - Psychic Frog (UB) - needs blue and black - Faithless Looting (R) - needs red I have Scalding Tarn in hand which can fetch Island or Mountain, and Raucous Theater which can make red and black but enters tapped. For optimal mana: - If I fetch **Swamp** now, I'll have black mana for Emperor of Bones, but still need blue for Psychic Frog and red for Faithless Looting. - If I fetch **Island** now, I'll have blue for Psychic Frog, but still need black for both black spells. - **Undercity Sewers** or **Watery Grave** give me both colors but have drawbacks. Actually, looking at my hand again, I have **Raucous Theater** which can make red and black, and **Scalding Tarn** which can fetch Island or Mountain. So: - If I fetch a Swamp now, I can later use Scalding Tarn to get an Island for blue - Or I could fetch an Island now and use Raucous Theater for red/black But wait, Raucous Theater enters tapped, so if I play it next turn, I won't have mana this turn. Actually, I'm on turn 1. I should think about what I can do this turn vs future turns. I already used my land drop for Polluted Delta (which is now in graveyard). I can't play another land this turn. Let me reconsider. My current battlefield has nothing (Polluted Delta was sacrificed). I have 5 cards in hand: Emperor of Bones, Faithless Looting, Psychic Frog, Raucous Theater, Scalding Tarn. I need to fetch a land now. Let me think about my optimal mana base: - I need black for Emperor of Bones and Psychic Frog - I need blue for Psychic Frog - I need red for Faithless Looting The best choice is probably **Watery Grave** (Island Swamp). It gives me both blue and black, and I can pay 2 life to have it enter untapped. This gives me the colors I need most (blue and black for my creatures) while I can get red later from Raucous Theater or Scalding Tarn. Actually, looking at my options more carefully: - **Watery Grave** is best because it enters untapped if I pay 2 life, giving me both blue and black - **Undercity Sewers** enters tapped and gives both colors but surveils - **Swamp** or **Island** only give one color I should choose Watery Grave. Let me pick the one with id p24 or p25.

thinkingMiMo Minimal

Now I need to decide whether to pay 2 life to have Watery Grave enter untapped, or let it enter tapped. I should pay the 2 life to have it untapped so I can use it this turn if needed, though I won't have any spells to cast this turn since I already used my land drop. But it's still better to have it untapped for next turn.

Paid 2 life to have Watery Grave enter untapped on Turn 1 postcombat main phase with no instant-speed plays available for 1 mana. The hand contains Emperor of Bones (1B), Faithless Looting (R), Psychic Frog (UB), Raucous Theater, and Scalding Tarn — none of which can be meaningfully used with a single untapped UB source before Turn 2.

Analysis

Action taken: Paid 2 life to have Watery Grave enter untapped

Better line: Let Watery Grave enter tapped, saving 2 life. It would be untapped by Turn 2 when the player can actually use multiple mana for their 2-drop spells.

I need to decide whether to pay 2 life for Watery Grave to enter untapped. Looking at the game state: - I'm at 20 life - I have no permanents on the battlefield yet - I have no mana available - I want to cast Emperor of Bones (1B) next turn, which needs black mana Paying 2 life to have Watery Grave enter untapped is definitely worth it. This gives me untapped black/blue mana for next turn, allowing me to cast Emperor of Bones on turn 2. The 2 life is negligible compared to having functional mana.

I'm now on turn 2. I have: - Watery Grave untapped (can make U or B) - Two lands in hand: Raucous Theater (enters tapped, makes B/R) and Scalding Tarn (fetches Island/Mountain) - Spells: Emperor of Bones x2, Faithless Looting, Psychic Frog I need to decide which land to play this turn. My options: 1. **Raucous Theater** - Enters tapped, but I already have untapped mana from Watery Grave 2. **Scalding Tarn** - Can fetch a land, but I'll have to sacrifice it I should play Raucous Theater this turn because: - It gives me red mana for Faithless Looting (I only have black/blue from Watery Grave) - It enters tapped, but I can still use it next turn - Scalding Tarn can be played later when I need specific colors Let me play Raucous Theater.

Now I need to see if there's a trigger when Raucous Theater enters. It has "When this enters, surveil 1."

Playing Raucous Theater (enters tapped) on turn 3 wastes the entire turn with no play, when Scalding Tarn could enter untapped and be cracked to enable casting Psychic Frog or Emperor of Bones this turn. With only 1 untapped land (Watery Grave), playing a tapped land means 0 additional mana this turn.

Analysis

Action taken: Played Raucous Theater, which enters tapped, leaving only 1 mana available and no 2-mana play possible on turn 3.

Better line: Play Scalding Tarn, crack it for a Swamp (or similar), then cast Psychic Frog (UB) or Emperor of Bones (1B) this turn. Save Raucous Theater for a turn where the tempo loss matters less.

I'm on turn 3 with 2 untapped lands. I need to make a strategic play. Looking at my options, I should play Bloodstained Mire to fetch a land and then cast Emperor of Bones. However, I need to consider the mana cost carefully. Emperor of Bones costs 1B, which means I need one black mana and one colorless mana. I have Watery Grave (can make black or blue) and can fetch either Swamp or Mountain with Bloodstained Mire. Let me play Bloodstained Mire first:

thinkingMiMo Minimal

I need to choose which land to fetch with Bloodstained Mire - Swamp or Mountain. Looking at my mana situation: - Watery Grave can make black or blue - Raucous Theater can make black or red (and is already on the battlefield) - I need black mana for Emperor of Bones I should fetch a Swamp to have more black sources available. This gives me: - Watery Grave (U/B) - Raucous Theater (B/R) - Swamp (B) This provides excellent mana fixing for both my black spells and allows for red for Faithless Looting.

I need to select a Swamp from the library. Looking at the options: - Blood Crypt (Swamp Mountain) - p28 - Steam Vents (Island Mountain) - p30 - Swamp (basic) - p39 - Undercity Sewers (Island Swamp) - p26, p27 - Watery Grave (Island Swamp) - p25 I should choose the basic Swamp (p39) to have a reliable black source that comes in untapped and doesn't have any entering tapped or life payment complications. This gives me good mana stability.

I'm now in postcombat main phase with 3 untapped lands: - Swamp (p41) - can make black - Watery Grave (p32) - can make blue or black - Raucous Theater (p22) - can make black or red I have 4 cards in hand: - 2x Emperor of Bones (1B) - can cast with my black mana - Faithless Looting (R) - can cast with Raucous Theater's red mana - Psychic Frog (U/B) - needs both blue and black mana I should cast Emperor of Bones this turn since I have the mana available. Let me cast one Emperor of Bones. I need to use 2 black mana sources to pay for 1B (1 colorless + 1 black). Let me cast Emperor of Bones:

Emperor of Bones was chosen over Psychic Frog when both could be paired with Faithless Looting this turn.

Emperor of Bones was chosen over Psychic Frog when both could be paired with Faithless Looting this turn. Psychic Frog is generally the stronger card - it synergizes beautifully with Faithless Looting (discard to grow), threatens card draw on combat damage, and can gain flying for evasion. Emperor of Bones lacks good reanimation targets currently.

Analysis

Action taken: Cast Emperor of Bones

Better line: Cast Psychic Frog ({U}{B}), then Faithless Looting ({R}) to draw 2 and discard 2 - discards can pump Frog and stock the graveyard for later use.

gameMiMo Minimal casts Emperor of Bones from hand

thinkingMiMo Minimal

I notice that my lands are tapped! Raucous Theater and Watery Grave are tapped, but the Swamp (p41) is still untapped. I only have one untapped land now, which can only produce black mana. Emperor of Bones costs 1B, which means I need one black mana and one colorless mana. The Swamp can only produce black mana, not colorless. Wait, I'm looking at this wrong. The cost is {1}{B}, which means I need: - 1 colorless mana (can be produced by any land) - 1 black mana (must be produced by a land that can make black) But my only untapped land is the Swamp, which can only produce black mana. So I can only get black mana, not the colorless mana needed for the "1" part. Actually, let me reconsider. In Magic, the Swamp produces {B} (black mana), but I can also use it to pay for the colorless portion of a spell because any mana can be used to pay for colorless costs. So if I tap my Swamp for {B}, I can use that black mana to pay for the {1} part, and I still need another source for the {B} part. Wait, that's not right either. The Swamp produces {B}, which is specifically black mana. For a spell costing {1}{B}, I need: - One mana of any color (including black) OR a colorless mana source - One black mana So if I tap my Swamp for {B}, I can use that to pay for the {1} part, but I still need a source for the {B} part. But I have no other untapped lands! I made a mistake. I should have tapped my Swamp before casting Emperor of Bones, or I should have untapped my other lands somehow. Let me cancel this cast and reconsider.

I need to check if I can cast anything else. Looking at my board, I see Raucous Theater and Watery Grave are tapped, but I should be able to tap the Swamp (p41) to get black mana, then use that to pay for part of Emperor of Bones. Let me check the actual game state. Looking at the board, I see: - Raucous Theater: tapped - Swamp: NOT tapped (false) - Watery Grave: tapped So the Swamp is actually untapped! Let me try casting Emperor of Bones again and tap the Swamp for mana as part of the payment.

Casting Snapback (via alternate cost of exiling a blue card) to bounce Emperor of Bones, a 2/2 summoning sick creature that costs only {1}{B} to replay. This is a 2-for-0 card disadvantage (Snapback + exiled blue card) to delay a cheap creature by one turn. Emperor of Bones isn't an immediate lethal threat.

Analysis

Action taken: Cast Snapback via alternate cost to bounce Emperor of Bones

Better line: Pass the turn and save Snapback and the blue card for a more impactful moment, such as bouncing a larger threat or protecting a combo turn. The 2/2 Emperor of Bones doesn't warrant spending two cards to delay by one turn.

minor blunder

Using Snapback's alternative cost (exiling a blue card from hand) to bounce a 2/2 Emperor of Bones that the opponent can simply replay next turn for 1B is a poor use of resources. This effectively costs two cards (Snapback + exiled blue card) to temporarily remove a small creature. With no lands in play and being in a desperate position, conserving resources for a more impactful use would be better.

Analysis

Action taken: Cast Snapback (exiling a blue card) to bounce Emperor of Bones, a 2/2 that the opponent can cheaply replay next turn.

Better line: Hold Snapback for a more threatening target or a situation where the tempo gain matters more. The opponent will simply replay Emperor of Bones next turn, making this a 2-for-0 card disadvantage for minimal tempo gain.

Using Snapback's alternative cost (exiling a blue card from hand) to bounce Emperor of Bones, a 2/2 that the opponent can easily recast next turn for {1}{B}. GPT52 Memoir is already severely resource-constrained with zero lands in play, and exiling a useful blue card for a temporary bounce of a small creature is questionable card economy. The opponent's lands are mostly tapped this turn anyway, limiting Emperor's immediate threat.

Analysis

Action taken: Cast Snapback (exiling a blue card) to bounce Emperor of Bones

Better line: Let the Lotus Bloom time counter resolve and save resources. Emperor of Bones is not immediately threatening since the opponent lacks mana to adapt it this turn, and the bounce is temporary. Preserving the blue card (likely Flare of Denial or a creature) could be more valuable later.

Now I'm on turn 4 with 3 untapped lands: - Raucous Theater (p22) - can make black or red - Swamp (p41) - can make black - Watery Grave (p32) - can make blue or black And I have Scalding Tarn in hand (p23 and p46). I should cast Emperor of Bones now. I need to pay 1B, which means I need 2 mana total (one black for the B, and one of any color for the 1). I can tap: - Swamp (p41) for black - use this for the B - Watery Grave (p32) for black - use this for the 1 Or I could tap: - Raucous Theater (p22) for black - use this for the B - Swamp (p41) for black - use this for the 1 Let me cast Emperor of Bones:

thinkingMiMo Minimal

I see the issue - Raucous Theater and Watery Grave are both tapped again, and only the Swamp is untapped. But I only have one untapped land, and I need to pay 1B (2 mana total). I can't cast Emperor of Bones this turn because I don't have enough untapped lands. Wait, let me reconsider. The board shows: - Raucous Theater: tapped (p22) - Swamp: NOT tapped (p41) - Watery Grave: tapped (p32) So I have only 1 untapped land, but I need 2 mana. I cannot cast Emperor of Bones with only 1 land untapped. Let me cancel this cast and pass priority.

I only have 1 untapped land, so I cannot cast Emperor of Bones (needs 2 mana) or Psychic Frog (needs 2 mana). I could cast Faithless Looting which costs R (1 mana), but Raucous Theater is tapped and I don't have a red source untapped. Actually, let me check my battlefield again. The Swamp (p41) can only produce black mana. I need red for Faithless Looting. I can't cast anything this turn with only 1 untapped land that produces black. Let me pass the turn.

gameMiMo Minimal puts Emperor of Bones from stack onto the Battlefield

— Beginning of Combat —

thinkingMiMo Minimal

Great! Emperor of Bones is now on the battlefield! Its ability triggers at the beginning of combat: "At the beginning of combat on your turn, exile up to one target card from a graveyard." I need to choose a target card from a graveyard to exile. Looking at the graveyard: - Bloodstained Mire - Goblin Charbelcher - Polluted Delta - Snapback I should exile a card that could be useful to my opponent. Goblin Charbelcher seems like a potentially powerful card. However, I should also consider that exile effects can be beneficial for me later with Emperor of Bones' ability to bring creatures back. Actually, Emperor of Bones says "put a creature card exiled with {this} onto the battlefield" - so I need to exile a creature card to potentially bring it back. Looking at the graveyard, Snapback is a creature (2/1), and Goblin Charbelcher is an artifact creature. Let me check what they are. I should exile Snapback since it's a creature card, and I could potentially cast it later for free with Emperor of Bones. Actually wait, let me check the text again. Goblin Charbelcher is an artifact creature (2/4). Snapback is also a creature. Both could be targets. I'll exile Snapback since it's a smaller creature that might not be as threatening to reanimate, but I want to keep the ability for future turns.

minor blunder

Emperor of Bones exiled Snapback from opponent's graveyard instead of Goblin Charbelcher.

Emperor of Bones exiled Snapback from opponent's graveyard instead of Goblin Charbelcher. The opponent's deck includes Tameshi, Reality Architect which can return artifact cards from graveyard to battlefield. Goblin Charbelcher is a major win condition/combo piece that could be recurred, while Snapback is a situational bounce spell with an alternate cost (exile a blue card) making the graveyard copy less critical.

Analysis

Action taken: Exiled Snapback from opponent's graveyard with Emperor of Bones trigger

Better line: Exile Goblin Charbelcher to deny the opponent potential recursion of their combo piece via Tameshi or other graveyard-to-battlefield effects

gameMiMo Minimal - Ability triggers: Emperor of Bones - At the beginning of combat on your turn, exile up to one target card from a graveyard. - targeting Snapback

gameMiMo Minimal moves Snapback from graveyard to the exile zone (source: Emperor of Bones)

thinkingMiMo Minimal

I'm now in postcombat main phase of turn 4. I have: - Emperor of Bones on battlefield with Snapback exiled under it - 1 untapped land (Swamp) - 2 Scalding Tarns in hand (p23 and p46) - My hand: Emperor of Bones, Faithless Looting, Psychic Frog, 2x Scalding Tarn I can play a Scalding Tarn this turn. Scalding Tarn can fetch Island or Mountain. I need to think about what colors I need: - I already have black mana from Swamp - I need blue for Psychic Frog - I need red for Faithless Looting - I need more black sources for Emperor of Bones I should fetch an Island or Mountain. Let me fetch an Island to get blue mana for Psychic Frog:

I need to choose an Island or Mountain from my library. Looking at the options: - Blood Crypt (Swamp Mountain) - p28 - Island (basic) - p29 - Steam Vents (Island Mountain) - p30 - Undercity Sewers (Island Swamp) - p26, p27 - Watery Grave (Island Swamp) - p25 I should choose Island (p29) because: 1. It gives me untapped blue mana 2. I need blue mana for Psychic Frog 3. Basic lands are reliable and come in untapped 4. This gives me good mana fixing for my blue/black deck

thinkingMiMo Minimal

I see that I'm not on turn 4 anymore - it looks like my opponent (GPT52 Memoir) is now on their turn (Turn 4 Beginning/Upkeep). I can see that: 1. I have Emperor of Bones (p18) on the battlefield with 2 untapped lands: Island (p50) and Swamp (p41) 2. My battlefield has 5 lands total now 3. My opponent has GPT52 Memoir as active player I can see there's a stack with an ability targeting GPT52 Memoir. I can also see that Emperor of Bones has an ability I can activate: "{1}{B}: Adapt 2" This means I can pay 1B to put two +1/+1 counters on Emperor of Bones. This will trigger its other ability: "Whenever one or more +1/+1 counters are put on {this}, put a creature card exiled with {this} onto the battlefield under your control with a finality counter on it." I exiled Snapback earlier, so if I adapt, I can put Snapback onto the battlefield! Let me do that. I need to pay 1B: - Island (p50) can make blue mana, but I need black mana for the B part - Swamp (p41) can make black mana - I can tap both to get 1 black and 1 blue, but I need 1B (1 black for the B, and 1 of any color for the 1) Wait, I can use: - Swamp (p41) for black mana - use for the B - Island (p50) for blue mana - use for the 1 This works! Let me activate Emperor of Bones' adapt ability:

I need to understand what's happening. I see Emperor of Bones is now 4/4 with 2 +1/+1 counters, and it's not summoning sick anymore. This suggests it was already adapted. I need to see where Snapback went. It shows up in GPT52 Memoir's exile zone, not mine. This is strange since I had exiled it with my Emperor of Bones. Let me check what abilities are available and try to understand the situation better. Looking at my board: - Emperor of Bones (4/4, 2 counters, no summoning sickness) - 4 untapped lands: Island, Raucous Theater, Swamp, Watery Grave - I have Snapback in my hand originally Let me check if Snapback is actually still exiled with Emperor of Bones or if something else happened. I should try to activate Emperor of Bones' ability first.

moderate blunder

Activated Adapt 2 on Emperor of Bones that already has +1/+1 counters.

Activated Adapt 2 on Emperor of Bones that already has +1/+1 counters. Adapt explicitly does nothing if the creature already has +1/+1 counters on it, so this wastes {1}{B} (2 mana) for zero effect. The Emperor is already 4/4 with two +1/+1 counters.

Analysis

Action taken: Activated Adapt 2 on Emperor of Bones that already had +1/+1 counters, wasting 2 mana for no effect.

Better line: Play Scalding Tarn (land drop), then cast Psychic Frog ({U}{B}) to develop another threat while still having mana available for Fatal Push or other plays. Alternatively, cast Faithless Looting to improve hand quality, or deploy the second Emperor of Bones.

Now I understand! Looking at the log: 1. On turn 4, I activated Adapt 2 on Emperor of Bones (which had no counters) 2. This triggered the ability to put a creature card exiled with Emperor of Bones onto the battlefield 3. Snapback was exiled, so it should have been put onto the battlefield But I see that Snapback is now in GPT52 Memoir's exile, not in my exile with Emperor of Bones. This suggests that maybe the Snapback was already on the battlefield and then got exiled, or there's some confusion about what's happening. Wait, looking at the log more carefully, I see "MiMo Minimal activates: Adapt 2" twice. This suggests I might have already activated Adapt 2 earlier, and now I'm trying to activate it again. But Emperor of Bones can only adapt if it has no +1/+1 counters, and I can see it has 2 counters already. Let me look at the board state more carefully. Emperor of Bones shows 2 +1/+1 counters, so it already adapted. I cannot adapt it again. But wait, there's a stack with an ability on it. Let me think about what to do. I have: - Emperor of Bones (4/4 with 2 counters) - 4 untapped lands - Cards in hand that I can cast I should cast Psychic Frog since I have the mana: - Island (p50) can make blue - Swamp (p41) can make black - I need {U}{B} which is exactly what I have! Let me cast Psychic Frog:

Player was casting Disrupting Shoal to counter Psychic Frog (mana value 2) but timed out and failed to select a blue car…

Player was casting Disrupting Shoal to counter Psychic Frog (mana value 2) but timed out and failed to select a blue card to exile. This means Disrupting Shoal fails and Psychic Frog resolves. Psychic Frog is one of the most dangerous threats in Modern - it draws cards on combat damage, grows with discards, and can gain flying. Letting it resolve while also wasting the Disrupting Shoal is devastating.

Analysis

Action taken: Timed out without selecting a card, causing Disrupting Shoal to fail and Psychic Frog to resolve.

Better line: Exile Fallaji Archaeologist (mana value 2) to properly counter Psychic Frog with Disrupting Shoal, preserving Thundertrap Trainer for later card selection.

Fatal Push was cast with no enemy creatures on the battlefield, meaning the only valid target is MiMo's own Emperor of Bones (4/4). This destroys their own primary threat for absolutely no benefit.

Analysis

Action taken: Cast Fatal Push, presumably targeting their own Emperor of Bones 4/4

Better line: Pass priority and proceed to combat, attacking with the 4/4 Emperor of Bones to pressure the opponent's 20 life total.

thinkingMiMo Minimal

I need to decide whether to pay 2 life for Watery Grave to enter untapped. I have 14 life currently. If I pay 2 life, I'll have 12 life. But this will give me untapped land which I can use this turn. I should pay the 2 life because: 1. I need untapped land for this turn 2. 14 life is not too low yet 3. Having untapped land is more valuable than 2 life right now

I now have: - Emperor of Bones (4/4) with 2 +1/+1 counters - 1 untapped land (Watery Grave with p61, which I got from Scalding Tarn) - I have 12 life - I have Fatal Push in hand (can cast for {B}) I should cast Fatal Push. Looking at my board: - Island (p50) - tapped - Raucous Theater (p22) - tapped - Swamp (p41) - tapped - Watery Grave (p32) - tapped - Watery Grave (p61) - untapped (I can use this!) I can tap p61 (the untapped Watery Grave) to get {B} and cast Fatal Push.

I need to select a target for Fatal Push. The only target available is Emperor of Bones (p18), which is my own creature. I shouldn't target my own creature with Fatal Push. But maybe the game is asking me if I want to cast Fatal Push? Let me check what targets are available for Fatal Push. Actually, I think the issue is that I need to confirm the mana payment first. Let me see what's happening:

thinkingMiMo Minimal

I see! The only target available for Fatal Push is Emperor of Bones (my own creature), and I don't want to destroy my own creature. I should cancel this spell. Let me cancel by passing:

thinkingMiMo Minimal

I'm in combat phase now. I see there's an ability on the stack (Emperor of Bones' ability) asking me to select a card from a graveyard. The options are all the cards in my graveyard: - Bloodstained Mire - Disrupting Shoal - Goblin Charbelcher - Polluted Delta - Psychic Frog - Scalding Tarn - Scalding Tarn I should select a good target to exile. Looking at the options, I should probably exile something that's useful. Let me think about what makes sense: - Bloodstained Mire - fetch land, could be useful - Disrupting Shoal - counter spell, could be useful - Goblin Charbelcher - artifact that mills, not super useful - Polluted Delta - fetch land, could be useful - Psychic Frog - creature that I want to get back onto battlefield - Scalding Tarn - fetch land, could be useful I should probably exile Psychic Frog (p21) because that's the creature I want to bring back to the battlefield! Wait, but I'm trying to exile a card FROM the graveyard, and Psychic Frog is already in my graveyard. So if I exile it, it goes to exile zone. But then Emperor of Bones' ability will put a creature card exiled with Emperor of Bones onto the battlefield. But Psychic Frog is in my graveyard, not exiled with Emperor of Bones. I'm confused. Let me re-read the ability: "At the beginning of combat on your turn, exile up to one target card from a graveyard." So this is the beginning of combat ability that lets me exile a card from a graveyard. This doesn't trigger Emperor of Bones' other ability - it's just setting up potential targets for later. Then there's Emperor of Bones' second ability: "Whenever one or more +1/+1 counters are put on {this}, put a creature card exiled with {this} onto the battlefield under your control with a finality counter on it." I already used this ability when I adapted Emperor of Bones earlier, and it put Snapback onto the battlefield. But then something happened - maybe Snapback got bounced or removed? Actually, let me think about this differently. The stack shows "Ability" which could be Emperor of Bones' ability. Let me just pick a card to exile. I should exile something useful. Let me exile Disrupting Shoal (p54) since it's a counterspell that might be useful later.

moderate blunder

Emperor of Bones can only reanimate creature cards exiled with it.

Emperor of Bones can only reanimate creature cards exiled with it. Psychic Frog is the only creature among the exile targets and could be reanimated when Emperor adapts (already available for {1}{B}). Exiling Disrupting Shoal accomplishes essentially nothing - it's a non-creature and the opponent has no way to reuse it from graveyard.

Analysis

Action taken: Exiled Disrupting Shoal (a non-creature instant from opponent's graveyard)

Better line: Exile Psychic Frog from own graveyard, enabling reanimation via Emperor of Bones' adapt trigger to create a hasty Psychic Frog attacker

gameMiMo Minimal - Ability triggers: Emperor of Bones - At the beginning of combat on your turn, exile up to one target card from a graveyard. - targeting Disrupting Shoal

gameMiMo Minimal moves Disrupting Shoal from graveyard to the exile zone (source: Emperor of Bones)

I'm in the combat phase. I need to declare attackers. I have Emperor of Bones (p18) which is a 4/4 with 2 +1/+1 counters. It's not summoning sick, so I can attack with it. I should attack with Emperor of Bones. The opponent has no creatures on the battlefield (I can see their battlefield is empty). So I should attack for 4 damage. Let me declare Emperor of Bones as an attacker:

moderate blunder

Failed to attack with a 4/4 Emperor of Bones into an empty board.

Failed to attack with a 4/4 Emperor of Bones into an empty board. The opponent has no creatures to block, so this is 4 free damage (20% of opponent's remaining life). The timeout caused the player to skip their attack entirely.

Analysis

Action taken: No response — skipped the attack step without declaring any attackers.

Better line: Attack with Emperor of Bones for 4 unblockable damage, bringing the opponent from 20 to 16 life.

thinkingMiMo Minimal

I see the combat phase. I've declared Emperor of Bones as an attacker, and it's not blocked. The opponent has no creatures to block with. Now I can cast instants during the declare blockers step. I can see Fatal Push is available to cast ({B} mana cost). I have 1 untapped land (Watery Grave with p61) that I can tap for {B}. But I should think about whether it's worth it to cast Fatal Push right now. The opponent has no creatures on the battlefield, so there's nothing for me to destroy with Fatal Push. Even if I cast it now, it won't do anything since there are no targets. I should just pass and let the combat damage happen.

gameGPT52 Memoir loses 4 life at combat from Emperor of Bones

— Combat Damage —

— Postcombat Main —

thinkingMiMo Minimal

I'm now in the postcombat main phase. I see that GPT52 Memoir's life went from 20 to 16, which means Emperor of Bones dealt 4 combat damage to them! That's good. I can see I have a land drop available (land_drops_used: 1, but it's still my main phase so I might be able to play another land). I can see I have a tap land (p61) that's untapped. I also see Fatal Push is still available to cast ({B} mana cost). But again, there are no creatures on the opponent's side to target. I could try casting Faithless Looting from my graveyard using flashback, but that costs {2}{R} and I don't have red mana available. Let me think about what else I can do. I have: - Emperor of Bones (4/4) tapped - 6 lands total (5 tapped, 1 untapped) - 3 cards in hand - 12 life I should check what cards are in my hand: 1. Emperor of Bones (p34) - {1}{B} creature 2. Faithless Looting (p19) - {R} sorcery 3. Fatal Push (p55) - {B} instant I could cast another Emperor of Bones, but I already have one. I could cast Faithless Looting if I had red mana. I could cast Fatal Push but there are no targets. I think I should just pass and end my turn. Let me cast Fatal Push for value (even if there are no targets, I can cast it and maybe it will do something). Or I should just pass. Actually, let me think about this more carefully. I have an untapped Watery Grave (p61) that I can tap for {B} and cast Fatal Push. But what would be the target? There are no creatures on the battlefield from GPT52 Memoir. So Fatal Push would have no legal targets and would be countered on resolution. Let me just end my turn. I'll pass priority:

major blunder

Player timed out and took no action with Lotus Bloom as their only mana source and no lands in play.

Player timed out and took no action with Lotus Bloom as their only mana source and no lands in play. They had castable spells that would develop their board position against an opponent's 4/4 Emperor of Bones. Lotus Bloom is a one-shot resource that was wasted this turn. Fallaji Archaeologist would have provided a blocker, milled cards for future value, and enabled Flare of Denial as free countermagic.

Action taken: Timed out and passed without casting anything, wasting the Lotus Bloom turn.

Better line: Sacrifice Lotus Bloom for {U}{U}{U}, cast Fallaji Archaeologist for {1}{U} (leaving {U} open), getting a 0/3 blocker, milling 3 cards, potentially finding a spell, and enabling Flare of Denial. Alternatively, cast Tameshi for {2}{U} to develop a bigger threat.

Casting Fallaji Archaeologist (0/3 for 2 mana) instead of Tameshi, Reality Architect (2/3 for 3 mana) when Lotus Bloom provides exactly 3 mana. Tameshi is a bigger body (relevant blocking Emperor of Bones 4/4), uses mana more efficiently (no waste), and could potentially recur Goblin Charbelcher from graveyard later. Both serve as blue creatures for Flare of Denial.

Analysis

Action taken: Cast Fallaji Archaeologist for {1}{U}, leaving 1 mana unused from Lotus Bloom

Better line: Cast Tameshi, Reality Architect for {2}{U}, using all 3 mana from Lotus Bloom efficiently, getting a bigger body and potential graveyard recursion

I see what's happening now! GPT52 Memoir just: 1. Solved Lotus Bloom (suspended card) - they cast it for free and got 3 mana 2. Sacrificed it to add mana 3. Cast Fallaji Archaeologist from their hand I should pass priority to let them continue their turn and see what they do next.

I see that GPT52 Memoir just cast Fallaji Archaeologist, and its enter-the-battlefield ability is on the stack (milling 3 cards). This is a good opportunity to cast Fatal Push to destroy it before its ability resolves! Fallaji Archaeologist is a creature with mana value 3 (based on typical costs for this type of card). Since I have revolt (a permanent left the battlefield this turn - Scalding Tarn), I can destroy creatures with mana value 4 or less. Let me cast Fatal Push targeting Fallaji Archaeologist:

Perfect! I can target Fallaji Archaeologist (p3) - it's controlled by GPT52 Memoir. Since I have revolt (a permanent left the battlefield this turn - Scalding Tarn), I can destroy creatures with mana value 4 or less. Fallaji Archaeologist is likely mana value 3, so it will be destroyed.

I see that it's now my turn (Turn 6). I have: - Emperor of Bones (p18) on battlefield, untapped, with 2 +1/+1 counters (4/4) - 6 untapped lands - I can see Fallaji Archaeologist is now in my graveyard (p3 and p70), which means Fatal Push destroyed it! My hand has: - Emperor of Bones (p34) - {1}{B} - Emperor of Bones (p73) - {1}{B} - Faithless Looting (p19) - {R} I have multiple Emperor of Bones cards in hand. I should probably play another Emperor of Bones to get another body on the battlefield. But let me think about what's best: 1. Play Emperor of Bones (p34) for {1}{B} - this gives me another 2/2 creature that can adapt later 2. Play Emperor of Bones (p73) for {1}{B} - same as above 3. Play Faithless Looting (p19) for {R} - draw 2, discard 2 I should cast an Emperor of Bones. I have 6 untapped lands, so I can easily pay {1}{B}. Let me cast one.

minor blunder

Playing Emperor of Bones before casting Faithless Looting is suboptimal sequencing.

Playing Emperor of Bones before casting Faithless Looting is suboptimal sequencing. Faithless Looting costs only {R} and draws 2 cards while discarding 2, providing crucial information about what's available before committing to a play. If this was the activate option (Adapt), it does nothing since the Emperor already has +1/+1 counters. If casting a second copy, the legend rule would destroy the existing 4/4 to get a fresh 2/2, losing the +1/+1 counters.

Analysis

Action taken: Chose Emperor of Bones (either activating Adapt on the 4/4 or casting a second copy) before seeing Faithless Looting draws.

Better line: Cast Faithless Looting first for {R} to draw 2 cards and see more options, then decide whether to cast Emperor of Bones or take a different line based on what was drawn.

gameMiMo Minimal casts Emperor of Bones from hand

thinkingMiMo Minimal

I need to reconsider. Looking at the board state: - Emperor of Bones p18 (untapped, 4/4) - Emperor of Bones p34 (tapped, 2/2) - this was already cast - Emperor of Bones p73 - this is still on the stack and needs mana I have only 1 untapped land (p61 - Watery Grave). For a {1}{B} spell, I need 2 mana but only have 1. I should cancel this spell since I can't pay for it.

I should exile a good creature from the graveyard. Psychic Frog (p21) is a great choice because it has useful abilities (draw on damage, pump, flying). Let me exile it.

— Declare Attackers —

thinkingMiMo Minimal

I see I'm in the combat phase and need to declare attackers. I have: - Emperor of Bones p18 (4/4, untapped, summoning sick = false) - Emperor of Bones p34 (2/2, tapped) - can't attack - Emperor of Bones p73 (2/2, untapped, summoning sick = true) - can't attack I can attack with p18 (4/4). GPT52 Memoir has no creatures on the battlefield, so I should attack for 4 damage.

moderate blunder

Failed to attack with a 4/4 Emperor of Bones into an empty board, missing 4 free damage against an opponent at 16 life.

Failed to attack with a 4/4 Emperor of Bones into an empty board, missing 4 free damage against an opponent at 16 life. The opponent has no creatures to block. This was a timeout/no response rather than a deliberate choice.

Analysis

Action taken: Did not declare any attackers (timed out).

Better line: Attack with the 4/4 Emperor of Bones for 4 unblocked damage, bringing the opponent from 16 to 12 life.

moderate blunder

Disrupting Shoal was cast to counter Thoughtseize (MV 1), but with no lands in play and no blue card with MV 1 in hand, …

Disrupting Shoal was cast to counter Thoughtseize (MV 1), but with no lands in play and no blue card with MV 1 in hand, the only possible X value is 0. Disrupting Shoal with X=0 cannot counter a spell with MV 1, so this wastes the Disrupting Shoal for nothing while Thoughtseize still resolves.

Analysis

Action taken: Cast Disrupting Shoal (which will have X=0) attempting to counter Thoughtseize (MV 1)

Better line: Let Thoughtseize resolve. Losing a card to Thoughtseize is bad but at least you keep Disrupting Shoal for a future spell that might have MV 0, or save it for when you have mana to hard-cast it with appropriate X value.

I need to select a card from GPT52 Memoir's hand. Let me look at the threats: - Disrupting Shoal - Counter spell (can exile a blue card to counter) - Flare of Denial - Counter spell (likely similar) - Goblin Charbelcher - Artifact that deals damage - Tameshi, Reality Architect - Creature that can return permanents - Whir of Invention - Artifact tutor The most threatening cards are the counterspells since they can stop my attacks. I'll take Flare of Denial:

minor blunder

Took Flare of Denial with Thoughtseize instead of the opponent's Goblin Charbelcher or a Whir of Invention.

Took Flare of Denial with Thoughtseize instead of the opponent's Goblin Charbelcher or a Whir of Invention. MiMo is the aggressor with 8 power on board vs opponent at 12 life, meaning the primary concern is the opponent comboing off with Charbelcher before being killed. Flare of Denial is less threatening since the opponent has no blue creatures to sacrifice for its alternate cost, and MiMo has almost nothing worth countering in hand (just Faithless Looting).

Analysis

Action taken: Took Flare of Denial from opponent's hand

Better line: Take Goblin Charbelcher to prevent the combo kill, forcing the opponent to use Whir of Invention (requiring 7+ mana) to find another copy from the library, buying crucial time to attack for lethal.

minor blunder

Emperor of Bones can only reanimate creature cards exiled with it.

Emperor of Bones can only reanimate creature cards exiled with it. Lotus Bloom is an artifact and cannot be reanimated. Fallaji Archaeologist is a creature in the opponent's graveyard that could be reanimated when Emperor adapts, providing card advantage (mill 3 + potential card selection).

Analysis

Action taken: Exiled Lotus Bloom with Emperor of Bones' combat trigger

Better line: Exile Fallaji Archaeologist instead, giving this Emperor of Bones a creature reanimation target when it adapts for {1}{B}

gameMiMo Minimal - Ability triggers: Emperor of Bones - At the beginning of combat on your turn, exile up to one target card from a graveyard. - targeting Goblin Charbelcher

I have Emperor of Bones abilities to activate. I can pay {1}{B} to adapt 2 on any of my Emperor of Bones. I have: - p18: 4/4 with 2 +1/+1 counters (already adapted) - p34: 2/2 with no counters - p73: 2/2 with no counters I should adapt the 2/2s to make them 4/4s. Let me adapt p34:

gameMiMo Minimal - Ability triggers: Emperor of Bones - Whenever one or more +1/+1 counters are put on Emperor of Bones, put a creature card exiled with Emperor of Bones onto the battlefield under your control with a finality counter on it. It gains haste. Sacrifice it at the beginning of the next end step.

I see that Psychic Frog (p21) has been put onto the battlefield with a finality counter! This is great - it was exiled earlier and now it's back with haste. Let me check the current phase and continue.

major blunder

The opponent is at 12 life with no creatures on the battlefield.

The opponent is at 12 life with no creatures on the battlefield. MiMo has two 4/4 Emperor of Bones, one 2/2 Emperor of Bones, and a 1/2 Psychic Frog. Without pumping, total attack damage is 4+4+2+1=11, one short of lethal. Discarding Faithless Looting to Psychic Frog would make it 2/3, bringing total damage to exactly 12 — lethal. The player timed out and failed to activate the ability.

Analysis

Action taken: No response (timeout) — did not activate Psychic Frog's discard ability.

Better line: Discard Faithless Looting to Psychic Frog to pump it to 2/3, then attack with all creatures for exactly 12 damage (lethal).

major blunder

Failed to declare any attackers against an opponent at 12 life with NO blockers on the battlefield.

Failed to declare any attackers against an opponent at 12 life with NO blockers on the battlefield. Had two 4/4 Emperor of Bones, one 2/2 Emperor of Bones, and a 1/2 Psychic Frog available to attack for 11 total damage, putting the opponent to 1 life. The Psychic Frog would also draw a card on combat damage. This was a timeout/no response that wasted a critical attack opportunity.

Analysis

Action taken: No attackers declared (timeout/no response)

Better line: Attack with all creatures (11 damage total) to put the opponent to 1 life, with Psychic Frog drawing a card on damage. This likely wins the game next turn.

I'm in the declare blockers phase. GPT52 Memoir has no creatures to block. I should use Psychic Frog's ability to discard Faithless Looting and put a +1/+1 counter on it, making it a 2/3. This will give me exactly 12 damage (4+4+2+2=12) to kill them.
