Looking at my opening hand: Flooded Strand (fetch land), Volcanic Island (dual land), three Force of Will (counterspells with alternative casting cost), Back to Basics (stax piece), and Dress Down (creature ability nullifier). This is actually a decent hand! Let me evaluate: - I have 2 lands (one fetchable, one dual) which gives me mana fixing - Three Force of Will gives me excellent protection - Back to Basics can be a powerful stax piece against non-basic land decks - Dress Down has utility against many creature strategies However, the hand has some issues: 1. I only have 2 lands - if I keep, I need to draw more lands quickly 2. No proactive plays in the early game besides Dress Down 3. Both Back to Basics and Force of Will require blue mana, which I have with Volcanic Island 4. Alternative Force of Will casting requires pitching a blue card - I have plenty of blue cards Since I'm on the draw (going second), I have an extra card anyway. This hand gives me disruption potential but lacks early threats. The fetch land gives me flexibility to find more colors if needed. I think I should KEEP this hand. The Forces give me protection, and I have the potential to disrupt my opponent's game plan. The risk is low since I'm on the draw and have a fetch land. I'll choose to keep (answer=false).

I see! My opponent is the active player on turn 1 and has already played a Tundra (a white-blue dual land). It's currently their precombat main phase and they have priority. They could be playing something or considering options. Since I have no priority right now, I should pass priority to let them continue. Let me use pass_priority to wait until I need to make a decision.

Great! Now I have playable cards. Let me get my action choices to see what I can do.
thinkingDSV3 Coach
I'm in my main phase (turn 1, going second). I have three land choices available: Prismatic Vista, Volcanic Island, and Flooded Strand. Looking at my hand again: I have Flooded Strand and Volcanic Island in hand, but Prismatic Vista is also showing as an option. Perhaps I have Prismatic Vista in my library/deck and I'm being given the option to play it? Actually, looking at my hand in the earlier state, I only had Flooded Strand and Volcanic Island. So Prismatic Vista must be coming from somewhere else - maybe it's in my library or there's some other effect. Let me think strategically: 1. **Flooded Strand** - Can fetch any Island, Plains, or Swamp. Gives me flexibility but costs 1 life. 2. **Volcanic Island** - Enters untapped, gives me blue and red without life cost. 3. **Prismatic Vista** - Can fetch any basic land, but requires 1 life and enters tapped. My current hand has three Force of Will (UU cost), Back to Basics (2U), and Dress Down (1U). All require blue mana. I want blue mana available for my spells. I should play **Volcanic Island** first. It gives me blue immediately without life loss and can produce red if needed later. Then next turn I can play Flooded Strand if I need another land. I'll choose the Volcanic Island.

Now I've played Volcanic Island. Let me check what actions I have available now.
thinkingDSV3 Coach
I have 1 untapped land (Volcanic Island) and no playable cards showing. Since I only have 1 mana available (blue or red), and my cheapest spell is Dress Down (1U), I can't cast it yet because I need 1 generic + 1 blue, which is 2 total mana. I should pass priority.

I have playable cards again. Let me check what's available.

Interesting - I still have Prismatic Vista as an option. It must be in my hand now (maybe I drew it?). Actually, I started with 7 cards, kept my hand, and haven't drawn yet. Maybe Prismatic Vista was in my hand but wasn't showing earlier? Or maybe I have a card that fetches it? Looking at my battlefield: I have Volcanic Island already played. I have 1 land drop remaining (since land_drops_used is 0). I can play either Prismatic Vista or Flooded Strand. I should play Flooded Strand now. It's a fetch land that can get me another land next turn if needed. It will give me more flexibility than Prismatic Vista (which only gets basics). Plus Flooded Strand can get non-basics like Volcanic Island (though that would be redundant), or other duals. Actually, Flooded Strand fetches: Island, Plains, or Swamp. Prismatic Vista fetches any basic land. Since I already have Volcanic Island (blue source), Flooded Strand could fetch a basic Island or Swamp if I need another blue source or black mana later. I'll choose Flooded Strand.

Now let me check what actions I have.

Now I have 2 untapped lands (Volcanic Island and Flooded Strand). I can activate Flooded Strand's ability to fetch a land. However, I should consider whether I want to do this now or later. I have 2 mana available (UU or UR). My cheapest spell is Dress Down (1U). I could cast it now if I want. But I don't see Dress Down in the playable choices yet - maybe I need to check again? Actually, looking at the response_type, it's "select" but only shows Flooded Strand's activate ability. That means I don't have any playable spells right now, or perhaps the server is only showing me the most immediate playable action. I should pass priority and see if I get other options. Let me choose_action(answer=false) to pass.

I'm in the End Turn step. I can activate Flooded Strand's ability at instant speed. Since I have 2 untapped lands and it's my opponent's turn next, I should consider whether to fetch now or wait. If I fetch now with Flooded Strand: - I can get an Island (basic) to have more blue sources - I pay 1 life - The fetched land enters tapped, so I won't have access to that mana this turn Since I already have Volcanic Island for blue mana, and I have Force of Will in hand (which I could cast for free by exiling a blue card if needed), I might want to keep Flooded Strand untapped for now. I could use it to fetch at the end of my opponent's turn if I need specific mana. Also, Back to Basics in my hand could make non-basic lands tap for only colorless, so having basic lands could be valuable later. But I think for now, I'll pass and not activate Flooded Strand. I'll save it for when I need specific mana.

Now it's my turn again. Let me check my action choices.
thinkingDSV3 Coach
Interesting! Now I have Prismatic Vista and Mountain as land options. I must have drawn these cards. I also still have Flooded Strand activation available. Let me think: - I can play Prismatic Vista (fetch any basic) - I can play Mountain (basic red) - I can activate Flooded Strand to fetch a land I already have Volcanic Island (blue/red) and Flooded Strand on the battlefield. I should play a land for turn. Which land should I play? Looking at my hand and strategy: - I have Force of Will (UU), Back to Basics (2U), Dress Down (1U) - I need blue mana - Mountain gives me red only - not helpful for my blue spells - Prismatic Vista can fetch any basic land, including Island I should play Prismatic Vista and fetch an Island. This gives me another blue source. Then I'll have Volcanic Island (U/R), Flooded Strand (can fetch), and Island (basic U). Actually wait - if I play Prismatic Vista, I can fetch immediately as part of its ability (it enters tapped and I sacrifice it to search). So I should play Prismatic Vista and fetch an Island.

Let me check my action choices.
thinkingDSV3 Coach
I see my life total dropped to 19hp, which means I paid 1 life for Prismatic Vista's ability. Now I have a choice of what land to fetch. However, the interface is only showing me Flooded Strand as an option. This might mean I need to fetch a land type? Actually, looking at the context, I'm in "Play instants and activated abilities" with only Flooded Strand showing. This suggests the game might be waiting for me to choose a land type for Prismatic Vista's search, but it's not showing me the options yet. Let me try passing priority to see if it prompts me for the land type choice.

Good! Now I have a GAME_TARGET action pending. This is likely asking me to choose what land to fetch with Prismatic Vista. Let me get my action choices.
thinkingDSV3 Coach
Perfect! I need to select a basic land card. I can choose from multiple Islands and Plains. Since I need blue mana for my spells (Force of Will, Back to Basics, Dress Down), I should fetch an Island. I'll choose the first Island option (index 0).

thinkingDSV3 Coach
Excellent! Now I have 3 untapped lands and I can cast spells. I see Dress Down (1U) and Thundertrap Trainer (1U) as options. Thundertrap Trainer is a 1/2 creature. Let me think about my strategy: - I have Force of Will (UU) in hand for counter magic - I have Back to Basics (2U) to potentially lock out my opponent's non-basic lands - Dress Down turns off creature abilities until end of turn - Thundertrap Trainer is a 1/2 creature that can crew vehicles I have 3 untapped lands available. I could cast both Dress Down and Thundertrap Trainer since they each cost 1U. However, I should consider my opponent's strategy. My opponent played Tundra on turn 1 and didn't play anything else. They might be playing a control deck or something that needs specific mana. For now, I think I should cast **Thundertrap Trainer**. Having a creature on board gives me early pressure and a blocker. I can save Dress Down for when it's more useful (to disrupt creature abilities). I'll cast Thundertrap Trainer.

thinkingDSV3 Coach
Now I need to choose how to pay for Thundertrap Trainer (1U). I have 3 untapped lands: Volcanic Island, Flooded Strand, and the Island I just fetched. I should use Volcanic Island and the Island for mana: - Volcanic Island can produce U - Island can produce U - That gives me UU, which covers the 1U cost Actually, 1U means 1 generic + 1 blue. So I need 2 total mana, with at least 1 blue. I'll use Volcanic Island for blue and Island for generic (or vice versa). Let me pass priority to see the mana payment options.

Interesting! Thundertrap Trainer has an "offspring" ability asking me to pay {4}. This is an optional cost when casting Thundertrap Trainer. Let me check what Thundertrap Trainer does by getting oracle text.

get_oracle_text(card_name=Thundertrap Trainer)
{
  "success": true,
  "name": "Thundertrap Trainer",
  "rules": [
    "Offspring {4} <i>(You may pay an additional {4} as you cast this spell. If you do, when this creature enters, create a 1/1 token copy of it.)</i>",
    "When {this} enters, look at the top four cards of your library. You may reveal a noncreature, nonland card from among them and put it into your hand. Put the rest on the bottom of your library in a random order."
  ]
}
thinkingDSV3 Coach
So Thundertrap Trainer has an optional "offspring" ability that costs {4} extra. If I pay it, I get a 1/1 token copy of Thundertrap Trainer when it enters. Do I want to pay {4}? That's a lot of mana on turn 1. I only have 3 lands untapped, so I can't pay {4} even if I wanted to. Plus, spending {4} extra seems too expensive early game. I'll choose not to pay the {4}. I'll answer false (no).

thinkingDSV3 Coach
Now I see Force of Will showing up! That's interesting. I have 1 untapped land left, and Force of Will costs {3}{U}{U} (5 mana total, with 2 blue). But wait, Force of Will has an alternative casting cost: "You may pay {1} and exile a blue card from your hand rather than pay Force of Will's mana cost." Maybe the game is showing me Force of Will because I can cast it using its alternative cost? Let me check the oracle text.
llm
get_oracle_text(card_name=Force of Will)
{
  "success": true,
  "name": "Force of Will",
  "rules": [
    "You may pay 1 life and exile a blue card from your hand rather than pay this spell's mana cost.",
    "Counter target spell."
  ]
}
thinkingDSV3 Coach
Yes! Force of Will has an alternative cost: pay 1 life and exile a blue card from hand. So I could cast Force of Will for free if I have a blue card to exile. But I'm trying to cast Thundertrap Trainer right now, not Force of Will. The game might be showing Force of Will because I can cast it as an instant in response to something, but I'm in my main phase casting Thundertrap Trainer. Actually, looking at the context: "Play instants and activated abilities" - this might be showing me things I can do while Thundertrap Trainer is on the stack. But I still need to pay for Thundertrap Trainer first. Let me check what lands I have available for mana. I see I have 1 untapped land left. I probably tapped some lands already. Let me get the game state to see my battlefield.

Great! Now I can see the current state: - I have 3 cards in hand showing as Force of Will (but actually I have 3 separate Force of Will cards in my hand!) - I have Back to Basics, Dress Down, and Mountain in hand - My battlefield: Volcanic Island (tapped), Flooded Strand (untapped), Island (tapped) - I have 1 untapped land: Flooded Strand The stack shows Thundertrap Trainer waiting to be paid for. I need to pay {1}{U} for it. My available lands: - Flooded Strand (untapped) - can produce white or blue mana I need to pay {1}{U}. I have Flooded Strand that can produce U. But I need {1} more generic mana. Hmm, I don't have any other untapped lands. Actually, I might have enough mana if I tap Flooded Strand for U, and I might have a floating mana from earlier? Let me check the mana pool. The action choices show "untapped_lands": 1, which means only Flooded Strand is untapped. But Thundertrap Trainer requires 2 mana total. I can't pay for it with just Flooded Strand. Wait, maybe I already tapped Volcanic Island earlier? Actually, Volcanic Island is tapped in the battlefield. Island is also tapped. So I only have Flooded Strand untapped. How did I think I could cast Thundertrap Trainer? I must have miscounted my available mana. I only have 1 untapped land (Flooded Strand) which can produce U or W. Thundertrap Trainer costs {1}{U} = 2 mana total, with at least 1 blue. I can't pay for it with just Flooded Strand. But the game let me attempt to cast it... maybe I can use Force of Will's alternative cost? No, Force of Will is a different spell. Actually, looking at the get_action_choices output again: I have Force of Will showing up multiple times. Maybe I should cancel casting Thundertrap Trainer since I can't pay for it? Actually, maybe I can use Flooded Strand's ability to fetch another land? But that land would enter tapped, so I still wouldn't have the mana this turn. I think I made a mistake. I should cancel casting Thundertrap Trainer. Let me try to cancel by choosing answer=false when I have a chance. First, let me see if I

Yes, Thundertrap Trainer is still on the stack. I need to either pay for it or cancel it. Since I can't pay {1}{U} with only Flooded Strand (1 mana source), I need to cancel the spell. I think the issue is that I'm trying to pay mana, but the game isn't prompting me for mana payment options. Let me try activating Flooded Strand's ability to fetch a land, but that land would enter tapped and wouldn't help me pay for Thundertrap Trainer this turn anyway. Actually, I should probably let Thundertrap Trainer be countered by insufficient payment. When I can't pay, the game should cancel the spell. Let me try passing priority without paying. Actually wait, I should check if I can tap Flooded Strand for mana. Maybe I can tap it for U, and that would give me 1 blue mana floating? But I need 2 total mana... Actually, let me check if I have any other way to generate mana. I only have Flooded Strand untapped. Let me try passing priority again to see if my opponent gets priority.

Interesting! The stack shows: 1. Flooded Strand ability (to search for land) 2. Force of Will (targeting Thundertrap Trainer) 3. Thundertrap Trainer So I activated Flooded Strand, and the game automatically let me cast Force of Will (probably using its alternative cost). Force of Will is targeting my own Thundertrap Trainer to counter it. Flooded Strand is in my graveyard now, so I sacrificed it. I need to resolve the land search ability. I still need to choose which land to fetch (Plains or Island). But also, I have Force of Will on the stack targeting my Thundertrap Trainer. I'm paying 1 life and exiling a blue card from hand to cast Force of Will with its alternative cost. Actually, looking at the stack order: Flooded Strand ability is on top, then Force of Will, then Thundertrap Trainer. So Flooded Strand will resolve first, then Force of Will, then Thundertrap Trainer. Force of Will will counter Thundertrap Trainer. That solves my problem of not having enough mana for Thundertrap Trainer! Let me pass priority to let things resolve.

Now I see the state! Ponder is on the stack. I have: - Volcanic Island (untapped) - can produce U or R - Island (tapped) My opponent has: - Tundra (untapped) - UW - Wasteland (untapped) - can destroy nonbasic lands - Phelia, Exuberant Shepherd (tapped) - 2/2 creature - Flooded Strand (untapped) - can fetch Plains/Island Also, I see that Thundertrap Trainer is in my graveyard, so Force of Will successfully countered it. Good! I have Ponder on stack needing {U}. I need to tap Volcanic Island for blue mana. Let me tap it. Actually, looking at the action choices, I only see Force of Will options. I think I need to tap a land for mana first. But I don't see an option to tap Volcanic Island. Actually, maybe I need to pay mana automatically? Let me try to pass priority to see if the game auto-taps.

Great! Ponder resolved! Now I need to order the top 3 cards of my library. I see: 1. Brainstorm (index 0) 2. Thundertrap Trainer (index 1) 3. Brainstorm (index 2) I need to choose the order to put them back on top of my library. The last one chosen will be topmost. I should think about what I want to draw next turn. I have: - 2 Brainstorms in the top 3 - 1 Thundertrap Trainer Brainstorm costs {U} and lets me draw 3 cards then put 2 back. That's great card selection. Thundertrap Trainer costs {1}{U} and has the Offspring ability. I'm playing a blue control deck. I should put Brainstorm on top so I can draw it next turn. Actually, I should put the best card on top. Let me think: I have 2 untapped lands (Volcanic Island and Island next turn). I could cast Brainstorm next turn with just Volcanic Island. Thundertrap Trainer costs {1}{U} which I could also cast with Volcanic Island + Island. Brainstorm is probably better because it gives me card selection. I'll put Brainstorm on top. Actually, I need to choose the order. The last card I choose will be on top. So I should choose: 1. Thundertrap Trainer (will be bottom) 2. Brainstorm (middle) 3. Brainstorm (top) Let me do that.

Good! I drew Brainstorm from Ponder and now I can cast it in my end step. I have 1 untapped land (Volcanic Island). Brainstorm costs {U}, which I can pay with Volcanic Island. But wait, I'm in my end step. Should I cast Brainstorm now or wait until my opponent's turn? Brainstorm at end step is good because: 1. It draws me 3 cards, giving me more options 2. I can put back cards I don't want 3. It happens at end of my turn, so my opponent doesn't get information before their turn I should cast Brainstorm. Let me do it.

Both my lands are tapped! That's why I can't pay for Brainstorm. I must have tapped them earlier. Wait, both Volcanic Island and Island are tapped. I must have tapped them to pay for something. Let me think... I tapped Island to pay for Flooded Strand activation (1 generic). I tapped Volcanic Island... hmm, maybe to pay for Ponder? But Ponder didn't resolve properly because of the auto-pass issue earlier. Actually, looking at the state: I have Brainstorm on stack but no mana to pay for it. Both lands are tapped. I can't pay {U}. I should pass priority and let Brainstorm get countered due to inability to pay? Or maybe I need to cancel it. Let me pass priority and see what happens.

Now I have a GAME_TARGET action. Let me check.
thinkingDSV3 Coach
Interesting! I need to select a card. This might be for Brainstorm's effect? Brainstorm says "Draw three cards, then put two cards from your hand on top of your library in any order." Actually, I think Brainstorm resolved! I drew 3 cards. Now I need to put 2 cards from my hand back on top. Let me check what cards I have in hand. The choices show: - Back to Basics - Brainstorm (drew one) - Force of Will x2 - Dress Down - Mountain - Thundertrap Trainer (from earlier?) - Ponder Wait, I have 9 cards shown. That's my hand after drawing 3 from Brainstorm. I need to put 2 cards back on top. I should put back cards I don't need right now. My hand has: 1. Force of Will x3 (good to keep for protection) 2. Back to Basics ({2}{U}) - good against opponent's nonbasic lands 3. Dress Down ({1}{U}) - good against creature abilities 4. Mountain (land) 5. Brainstorm (just drew) 6. Thundertrap Trainer (from earlier? maybe I drew it) 7. Ponder (from earlier?) Actually, I should check my library size. Before Brainstorm, library was 43. After drawing 3, it should be 40. I want to keep Force of Wills, Back to Basics, Dress Down. I can put back Mountain and maybe Thundertrap Trainer or Ponder. Actually, I should think about my mana situation. I have no untapped lands. Next turn I'll untap both lands. I have Volcanic Island (UR) and Island (U). I can cast: - Brainstorm (U) if I draw it - Dress Down (1U) - Back to Basics (2U) - Force of Will (3UU) but only with alternative cost I should put back cards that are less urgent. Mountain is a land, but I already have 2 lands. Thundertrap Trainer costs 1U, same as Dress Down. I'll put back Mountain and Thundertrap Trainer. First, select Mountain (index 6).

Now it's my turn! Let me check my action choices.
thinkingDSV3 Coach
Great! It's my turn 2, precombat main phase. I have 2 untapped lands (Volcanic Island and Island). My life is 14 (I paid life earlier). I have these playable cards: 1. Brainstorm ({U}) 2. Dress Down ({1}{U}) 3. Thundertrap Trainer ({1}{U}) 4. Ponder ({U}) I drew Thundertrap Trainer from Brainstorm (it was on top after I put it back). I also have Back to Basics and 3 Force of Wills in hand. My opponent has: - Tundra (UW, untapped) - Wasteland (untapped, can destroy nonbasic lands) - Flooded Strand (untapped) - Phelia, Exuberant Shepherd (tapped 2/2 creature) What should I play? - Brainstorm: Good for card selection, but I just cast one. Could draw more cards. - Dress Down: Turns off abilities until end of turn. Good against Phelia's abilities. - Thundertrap Trainer: 1/2 creature with Offspring ability. - Ponder: Good setup. I think I should play Thundertrap Trainer. It's a creature that can attack, and it has Offspring ability which could be useful later. Dress Down is situational - turns off abilities but also turns off my Force of Will's flash ability. Actually, let me think about the board: - Opponent has Wasteland that can destroy my Volcanic Island (nonbasic land) - Opponent has Phelia (2/2 creature) - I'm at 14 life, opponent at 17 Thundertrap Trainer is a 1/2 that can block Phelia. It's not great but it's a body. Actually, maybe I should play Brainstorm to dig for more answers. But I just cast Brainstorm last turn. Let me play Thundertrap Trainer. It's a creature that can apply pressure. Actually wait, I should consider my mana. I have 2 lands. Thundertrap Trainer costs {1}{U}. I need to tap both lands. Then I'll have no mana left for Force of Will alternative cost (exile blue card + pay 1 life). I have 3 Force of Wills in hand. If I tap out for Thundertrap Trainer, I won't be able to Force of Will anything. Better to keep mana open for Force of Will. I should play Brainstorm ({U}) instead

I see! Brainstorm is still on the stack! It hasn't resolved yet. I need to pay {U} for it. I have Volcanic Island untapped and Island tapped. I need to tap Volcanic Island for blue mana. But the game is only showing me Force of Will options. Maybe I need to pass priority to opponent? Or maybe there's a mana payment step. Actually, I think I need to pay mana first. Let me try passing priority to see if opponent responds.

Interesting! Now I have 10 cards in hand! I drew 3 from Brainstorm. My hand now has: 1. Back to Basics 2. Plains (new card!) 3. Force of Will x3 4. Dress Down 5. Mountain 6. Thundertrap Trainer 7. Swords to Plowshares (new card!) 8. Ponder That's 10 cards total. Brainstorm resolved! I need to put 2 cards back on top. I should put back cards I don't need immediately: - Plains (good land but I have red/blue colors already) - Mountain (already have red source) - Thundertrap Trainer (can play later) - Ponder (can play later) Actually, I should keep Swords to Plowshares for opponent's creatures. I should keep Force of Wills. Dress Down is situational. Back to Basics is good against opponent's nonbasic lands. I'll put back Plains and Mountain. First select Plains (index 1).

I have 8 cards in hand and need to discard down to 7 for cleanup step. I need to discard one card. My hand: 1. Back to Basics ({2}{U}) - good against opponent's nonbasic lands 2. Force of Will x3 - important counterspells 3. Dress Down ({1}{U}) - situational 4. Mountain (land) 5. Thundertrap Trainer ({1}{U}) - creature 6. Ponder ({U}) - card selection I should discard Mountain since I have Volcanic Island for red mana already. Select Mountain (index 5).

Now it's my turn 3. Let me check action choices.
thinkingDSV3 Coach
I'm at 7 life! I paid life earlier for something. It's my turn 3, precombat main. I have 2 untapped lands (both lands untapped). I can play: 1. Dress Down ({1}{U}) 2. Thundertrap Trainer ({1}{U}) 3. Ponder ({U}) I also have Back to Basics in hand ({2}{U}) and 3 Force of Wills. Opponent has: - 2 Tundras (UW) - Wasteland (can destroy nonbasic lands) - Island - Phelia, Exuberant Shepherd (3/3 with +1/+1 counter) - Quantum Riddler (4/6, summoning sickness) Quantum Riddler is a big 4/6 creature. I should consider playing Dress Down to turn off its abilities until end of turn. But Dress Down also turns off Force of Will's flash ability. Actually, maybe I should play Ponder to set up my draws. Or play Thundertrap Trainer as a blocker. Quantum Riddler is big (4/6). Thundertrap Trainer is 1/2, can't block it effectively. I think I should play Ponder to find answers. But I need to think about my mana. If I tap out for Ponder ({U}), I'll have 1 untapped land left for Force of Will alternative cost. Actually, I should check my lands: Volcanic Island (UR) and Island (U). Both untapped. If I play Ponder ({U}) tapping Island, I'll have Volcanic Island untapped for Force of Will alternative cost (exile blue card + pay 1 life). That's good. Let me play Ponder.

I have a GAME_TARGET action. Probably Ponder's look at top 3 cards.
thinkingDSV3 Coach
Ponder shows me top 3 cards: Ponder, Plains, Swords to Plowshares. I need to order them (last chosen will be top). I see the top 3 cards of my library: 1. Ponder (card) 2. Plains (land) 3. Swords to Plowshares (removal) I can either keep this order or shuffle. If I shuffle, I get a random new top card. Swords to Plowshares is good removal against opponent's creatures (Phelia 3/3 and Quantum Riddler 4/6). Plains is a land. Ponder is another cantrip. I should put Swords to Plowshares on top since I need removal. Then Plains, then Ponder. Actually, last chosen will be top. So I should choose in this order: 1. First: Ponder (will be bottom) 2. Second: Plains (middle) 3. Third: Swords to Plowshares (top) Let me select Ponder first.

Wait, I'm in cleanup step again? I'm at 8 cards and need to discard. I have 8 cards. I drew Swords to Plowshares from Ponder! That's good. But I need to discard down to 7. My hand: 1. Back to Basics 2. Force of Will x3 3. Dress Down 4. Swords to Plowshares (just drew) 5. Thundertrap Trainer 6. Swords to Plowshares (another one) I should discard Dress Down or Thundertrap Trainer. Probably Thundertrap Trainer since it's a weak creature. Dress Down can be useful against Quantum Riddler. Select Thundertrap Trainer (index 6).
