What a hand! Let me analyze this: **Hand:** Thraben Charm, Galvanic Discharge x2, Seasoned Pyromancer, Guide of Souls, Ocelot Pride x2 This hand has incredible synergy but one critical problem: **no lands**. A 7-card hand with zero lands is an automatic mulligan - even with amazing spells, we can't cast anything without mana sources. This was always meant to be. The universe has spoken - we must mulligan.

No lands in a 7-card hand — that was destined to be shuffled away. Let's see what fate has in store for us with 6 cards.

We drew 7 new cards and need to put 1 on the bottom (mulligan to 6). Let me evaluate: - **Sacred Foundry** - Dual land, essential for our RW deck - **Voice of Victory** - Let me check this card - **Guide of Souls** - Great 1-drop with energy/life synergy - **Phlage, Titan of Fire's Fury** - Powerful threat, but costs RRW and needs escape - **Plains** - Basic land, important - **Galvanic Discharge** - Good removal - **Thraben Charm** - Versatile but situational

Great hand analysis: - **Sacred Foundry** + **Plains** = 2 lands (need to keep both) - **Guide of Souls** = excellent turn 1 play - **Voice of Victory** = strong 2-drop with Mobilize and opponent can't cast on our turn - **Galvanic Discharge** = solid removal - **Phlage** = can't hardcast effectively (sacrifices itself), really needs escape with 5 graveyard cards - too slow/unreliable early - **Thraben Charm** = decent but situational I'll bottom **Phlage** - it requires escape to be useful and we won't have the graveyard for it early. The other 6 cards give us a solid curve with lands, a 1-drop, a 2-drop, and removal.

Interesting - we drew an Arid Mesa (fetchland)! Now I need to decide which land to play on turn 1. We want to play Guide of Souls (W) this turn. **Options:** - **Arid Mesa** - Fetchland that can find any Mountain or Plains. Best to play this to thin our deck and fix future mana. Can fetch Sacred Foundry if needed. - **Sacred Foundry** - Dual land, pay 2 life for untapped. - **Plains** - Free white mana, no life cost. Best play: **Arid Mesa** - we fetch a land (thinning the deck), and can get an untapped white source. We'll fetch for a basic Plains-type land to save life, or Sacred Foundry if we need both colors later. Actually, we already have Sacred Foundry and Plains in hand, so let's play Arid Mesa now, fetch a basic (Mountain or Plains), and save our dual lands for later. Wait - we need W for Guide of Souls. Let me play Arid Mesa and fetch for a white source.

I need a white source to cast Guide of Souls. I already have Sacred Foundry and Plains in hand. Let me fetch a **Mountain** - that way on turn 2 I can play Sacred Foundry (or Plains) and have access to both colors. Getting a Mountain now gives us W from hand + R from battlefield for future flexibility. Wait, actually: I need W right now for Guide of Souls turn 1.

Interesting - opponent has two Urza's Sagas (one at 2 lore counters, one at 1) and a Mox Opal. They also have a Mox Opal in the graveyard. This looks like an artifact-heavy strategy. Now for turn 2 planning: - I drew **Ocelot Pride** (shows as playable) - I have Guide of Souls on board - I need to play a land and a 1-drop creature **Optimal sequencing:** 1. Play **Sacred Foundry** (pay 2 life, comes in untapped) - gives us access to R and W. This lets us cast both Voice of Victory (1W) or hold up Galvanic Discharge (R) if needed. 2. Actually, wait - I should play Plains (free, no life) since I only need W this turn for Ocelot Pride. But Voice of Victory costs 1W, and I'd want to cast it turn 2. With Plains + Plains I have WW (2 mana) but Voice needs 1W which works! Hmm, but having R available would let me hold up Galvanic Discharge. Let me think... Turn 2: Play Sacred Foundry untapped (17 life), cast Ocelot Pride (W from Plains). Then attack with Guide of Souls. This saves Plains for turn 3 where I can play Voice of Victory with 3 mana. Actually, let me reconsider: If I play Plains now, I have WW. I can cast Ocelot Pride for W, and still have W open. Next turn play Sacred Foundry for 3 mana (WWR or WW+colorless). Voice of Victory costs 1W which I can pay with WW already this turn! Better plan: Play **Plains**, cast **Ocelot Pride** (W), then we still have W open. We could even cast Voice of Victory for 1W this turn! But we'd be tapped out. Let me think about what's better: - Cast Ocelot Pride now → Guide of Souls triggers (gain 1 life, get energy) → attack with Guide of Souls → Ocelot Pride triggers end step if we gained life (we did from Guide trigger!) - Or cast Voice of Victory → attack with both next turn Ocelot Pride is better turn 2 because: 1. Guide of Souls triggers on ETB → gain life + energy 2. Attack with Guide of Souls, potentially use energy to pump 3. End step: Ocelot Pride makes a cat token if we gained life (which we did!) Let me play Plains first, then Ocelot Pride.

Now I have 2 untapped lands (WW). I can cast Ocelot Pride (W) and still have W open, OR cast Voice of Victory (1W) tapping out. The better play is **Ocelot Pride** first: - Guide of Souls triggers → gain 1 life + get energy - We keep W open for... nothing useful actually - Then we can attack with Guide of Souls - End step: Ocelot Pride triggers (we gained life) → make a cat token → Guide of Souls triggers again on the cat → gain another life + more energy Actually wait - could I cast BOTH Ocelot Pride AND then Voice of Victory? Ocelot Pride costs W, Voice costs 1W. After Ocelot Pride I'd have W left, not enough for Voice (needs 1W = 2 mana). So no. What about Voice of Victory instead? It costs 1W, locks opponent out of casting during our turn, and has Mobilize 2 (creates 2 warriors when attacking). Those warriors entering would trigger Guide of Souls twice! But we can't attack with Voice until next turn anyway. Better to play Ocelot Pride: it's more synergistic with Guide of Souls, starts making tokens immediately at end step, and we can play Voice next turn with 3 mana available.

Attack with Guide of Souls! Ocelot Pride just entered so it's summoning sick, but Guide of Souls has been out since turn 1. Opponent has no creatures to block.

Interesting! Let me review: - My hand: Sacred Foundry, Thraben Charm (1W), Galvanic Discharge (R), Voice of Victory (1W), Ragavan (R) - 2 untapped Plains, no red source on board yet - Opponent has: Mox Opal, Urza's Saga (2 lore), Haywire Mite (summoning sick), Island - I have 2 energy Wait, I'm in combat but haven't played my land yet! The game jumped to combat from `my_turn`. I should have played a land first in precombat main. But now I'm already in declare attackers. Let me think about combat: I have 3 creatures (3 power total). Opponent has Haywire Mite (1/1) which is summoning sick so can't block. They also have Mox Opal and Island untapped. I should check what the opponent might have. With no blockers available, I should attack with all 3 creatures for 3 damage. Then in postcombat main, play Sacred Foundry and cast Ragavan. Actually wait - if I attack with all, Guide of Souls triggers on attack (can pay 3 energy for +2/+2 and flying). I have 2 energy, so not enough for the 3 energy cost. Let me attack with everything!

Wait - opponent is still at 19? Ocelot Pride has first strike so maybe damage hasn't resolved yet... No, we got to postcombat main so combat is done. Hmm, opponent might have had a blocker or something. I'm at 22 though (gained more life from something - maybe Ocelot Pride's lifelink?). Actually, looking at Ocelot Pride - it likely has lifelink. That's why I went from 21 to 22. And I gained life meaning Ocelot Pride end step trigger will fire again! But wait - opponent at 19 means only... let me recalculate. They were at 19 before combat, I attacked for 3 (1+1+1), they should be at 16. Unless something blocked. Let me check the log.

So Haywire Mite blocked Ocelot Pride! It died (Ocelot Pride has first strike likely, or just traded). Opponent gained 2 life from Haywire Mite death trigger. So opponent took 2 damage (Guide + Cat) but gained 2 from Mite: 19 - 2 + 2 = 19. Makes sense. Now in postcombat main with land drop available. I should play Sacred Foundry and then cast either Voice of Victory or Ragavan. Let me think: - Play Sacred Foundry untapped (pay 2 life, go to 20) → gives me R + W + W = 3 mana - Cast Voice of Victory (1W) - prevents opponent from casting on my turn, gives Mobilize 2 on attacks - OR cast Ragavan (R) - can dash for 1R too, but regular cast for R works Voice of Victory is amazing here - it shuts down opponent's interaction on my turn and creates 2 warriors when attacking (which trigger Guide of Souls twice for +2 life and +2 energy). That's incredible synergy. But wait - did Ocelot Pride survive? It was blocked by Haywire Mite 1/1. Ocelot Pride is 1/1...

Ocelot Pride has first strike! So it dealt 1 damage to Haywire Mite first, killing it before Haywire Mite could deal damage back. Ocelot Pride survives! Great. Now, optimal play: 1. Play Sacred Foundry (untapped, pay 2 life → 20 life) 2. Cast Voice of Victory (1W) → prevents opponent casting on my turn + Mobilize 2 3. Still have R open for Galvanic Discharge as removal if needed OR: 1. Play Sacred Foundry untapped 2. Cast Ragavan (R) → Guide of Souls triggers (+1 life, +1 energy) 3. Still have WW open for Voice of Victory or Thraben Charm Wait, I can cast BOTH Ragavan AND something else! Sacred Foundry gives me RWW (3 mana). Ragavan = R, Voice = 1W. That's R + 1W = 3 mana total. I can cast BOTH! Sequence: Play Sacred Foundry → Cast Ragavan (R) → Guide of Souls triggers → Cast Voice of Victory (1W) This is the best play. I get both threats on board!

Excellent board state! I'm at 23 life with 5 energy and 6 creatures (Guide of Souls, Ocelot Pride, 2 Cat Tokens, Ragavan, Voice of Victory). Opponent has Emry (1/2, summoning sick), Mox Opal, and Island. Their graveyard is loaded with artifacts. The stack has a delayed draw trigger (from Mishra's Bauble probably). There's also an Unholy Heat in their graveyard - they already used it. Let me count their graveyard for delirium: Artifact (Mox Opal, Haywire Mite is creature+artifact, Mishra's Bauble, Tormod's Crypt, Lavaspur Boots), Creature (Haywire Mite), Land (Urza's Saga x2), Sorcery... Instant (Unholy Heat). That's potentially 5+ types - they might have delirium. I should be careful about holding up removal. But right now on my upkeep, I don't need to cast anything. Let the Bauble draw resolve and proceed to my main phase where I'll plan my attack.

Precombat main! I drew Flooded Strand. My hand is Thraben Charm, Galvanic Discharge, and Flooded Strand. I should think about sequencing: - Opponent has Emry (1/2) and Mox Opal. Emry can tap to cast artifacts from graveyard (Mox Opal, Tormod's Crypt, Mishra's Bauble, Lavaspur Boots). - I could Galvanic Discharge Emry right now - I have 5 energy + the spell gives 3 more = 8 energy. I'd deal enough to kill Emry easily. - But do I want to spend Galvanic Discharge on Emry or save it? Emry is very dangerous as it lets them repeatedly cast artifacts from graveyard. Actually, killing Emry is very important. If Emry stays, they can rebuild extremely quickly. And with Voice of Victory, opponents can't cast spells during my turn - wait, let me check Voice of Victory's text.

Voice of Victory: "Your opponents can't cast spells during your turn." This is incredible! They can't interact during my turn at all. And Mobilize 2 creates 2 warriors on attack. So Emry can't tap to cast artifacts during my turn because of Voice of Victory. But on their turn, Emry is active. I should kill Emry to prevent that. Let me play Flooded Strand first (can fetch later), then use Galvanic Discharge on Emry. Actually, wait. I don't need to kill Emry right now. They can only use Emry on their turn. Let me think about the attack instead. My attackers: Guide of Souls (1/2), Ocelot Pride (1/1 first strike lifelink), 2 Cat Tokens (1/1), Ragavan (2/1), Voice of Victory (1/3 + Mobilize 2). That's 6 creatures + 2 warriors from Mobilize = potentially 8 creatures attacking. If I attack with everything, they have Emry (1/2) to potentially block. Let me think about the math: - Attack with all 6 creatures - Voice of Victory creates 2 tapped and attacking warriors (1/1 each) - Guide of Souls triggers for each creature entering (2 warriors = +2 life, +2 energy) - Total attacking power: 1 + 1 + 1 + 1 + 2 + 1 + 1 + 1 = 9 power - They can block 1 creature with Emry Actually, I have 5 energy now. With Guide of Souls, I can pay 3 energy to give a creature +2/+2 and flying. Very relevant. Let me think: should I Galvanic Discharge Emry before combat to ensure max damage? - Galvanic Discharge gives 3 energy (total 8), then I spend some to kill Emry - Emry is 1/2, so I need 2 damage minimum = spend 2 energy, keeping 6 OR I can save Galvanic Discharge for a bigger threat and just attack. Emry blocks something small. Hmm, Emry is their only blocker. If they block a Cat Token, that's only 1 damage prevented. I'd still deal 8 damage, putting them to 11. That's pretty good. But if I kill Emry now, I deal 9 damage (putting them to 10), AND deny them Emry for their turn. That seems better. Let me kill Emry with Galvanic Discharge, keeping the remaining energy for Guide of Souls pump.

Emry is dead! Now combat - opponent has NO blockers (just Mox Opal). Attack with everything! Voice of Victory will create 2 Warrior tokens (Mobilize 2), and Guide of Souls will trigger for each new creature entering. This is going to be devastating.

I need to target a creature for the +2/+2 and flying. Since there are no blockers, I should put it on the highest-power creature for max damage. Ragavan is already 2/1, making it 4/3 = +2 extra damage. Any other creature goes from 1 to 3 power = same +2 extra. Actually it doesn't matter for damage, but I should put it on Ragavan since it already deals combat damage trigger (exile top card of opponent's library and create a Treasure) - making sure it survives is nice. They're all unblocked though so it doesn't matter. Let me put it on Ragavan for the extra damage.

Opponent is at 8 life! I'm at 26. Combat damage dealt 11 damage (19 → 8). Ragavan's trigger is on the stack targeting the opponent. I also gained life from Ocelot Pride's lifelink (1 life). Beautiful. Let me pass priority and let things resolve. I should also get Ocelot Pride cat tokens from gaining life.

Incredible board state! I have 10 creatures, 30 life, 9 energy. Opponent at 8 life with only Island, Mox Opal, and Mox Amber on the battlefield, 2 cards in hand. My hand: Thraben Charm and Blood Moon. Let me think about this: - I have 10 creatures attacking. Opponent has no blockers. Even if they have removal, I'll still push through lethal. - Blood Moon would turn their nonbasic lands (they only have an Island which is basic) into Mountains. Not very impactful since they don't have nonbasic lands. It would affect my Sacred Foundry and Flooded Strand though. - Thraben Charm deals damage equal to twice the number of creatures I control (10 × 2 = 20!) to target creature. But they have no creatures. OR I could just attack with all 10 creatures for 12 damage (1+1+1+1+4+1+1+1+1+1 = 13 actually). Wait, let me count attacking power: Guide (1) + Ocelot (1) + Cat (1) + Ragavan (4) + Voice of Victory (1) + Cat (1) + Cat (1) + Warrior (1) + Warrior (1) + Cat (1) = 13 power. That's lethal against 8 life! Plus Voice of Victory will create 2 more Warriors via Mobilize, and Guide of Souls will trigger for each new creature entering. I don't need to play anything. Just go to combat and attack for lethal! Actually, wait - they have Mox Opal and Mox Amber for mana. They could have a counterspell or removal. But Voice of Victory prevents them from casting spells during my turn! So they literally can't do anything. Let me just attack.
