Overview:

This Mardu (RWB) deck leverages Isshin, Two Heavens as One to amplify attack-trigger value, focusing on token swarms, combat-phase multipliers, and damage amplifiers. Isshin acts as the strategy's core, doubling triggers from creatures like Adeline, Resplendent Cathar and Krenko, Tin Street Kingpin to flood the board with tokens. Secondary win conditions include Purphoros, God of the Forge/Impact Tremors burn and Aurelia, the Warleader extra-combat loops. The deck balances aggressive creature deployment with protective measures like Teferi's Protection and Clever Concealment.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Deploy mana rocks (Sol Ring, Arcane Signet), token generators (Ainok Strike Leader, Signal Pest), or value engines like Skullclamp. Cast Isshin ASAP to double triggers.
2. Token Avalanche (Turns 3-5): Attack with Isshin and token generators. Mondrak, Glory Dominus doubles token output, while Ogre Battledriver grants haste. Use Reconnaissance to protect attackers post-combat.
3. Finishers (Turns 5-8):
   • Combat Overkill: Amplify tokens with Fervent Charge, Akroma's Will, or Marshal of the Lost. Blade of Selves on key creatures creates exponential attackers.
   • Burn: Purphoros, God of the Forge and Impact Tremors drain opponents as tokens enter.
   • Extra Combats: Aurelia, the Warleader and Neriv, Heart of the Storm enable multi-phase attacks.

Mulligan Priorities:

• Keep hands with Isshin + 2-3 lands (including color-fixing).
• Prioritize early token generators (Krenko, Tin Street Kingpin, Hero of Bladehold) or protection (Lightning Greaves).
• Avoid hands lacking ramp or creatures with attack triggers.

Key Tips:

• Use Reconnaissance to untap attackers after damage, preserving blockers.
• Sacrifice tokens to Plumb the Forbidden for card draw while triggering death effects (e.g., Zurgo Stormrender).
• Equip Infantry Shield to high-power creatures for massive token generation on attack.

Weaknesses:

Critical

• Board wipes (e.g., Farewell) cripple the token-dependent strategy; limited recursion outside Eternal Witness-like effects.
• Anti-token tech (Torpor Orb, Cursed Totem) nullifies key triggers and token generation.

Moderate

• Spot removal on Isshin slows the engine, though protection (Swiftfoot Boots, Deflecting Swat) mitigates this.
• Stax effects (Ghostly Prison, Blind Obedience) delay critical mass of attackers.

Minor

• Lifegain strategies outpace incremental damage from tokens.
• Limited stack interaction beyond Deflecting Swat and Soul Partition.

Most Important Cards:

1. Isshin, Two Heavens as One (Doubles attack triggers)
2. Mondrak, Glory Dominus (Token multiplier)
3. Purphoros, God of the Forge (Burn engine)
4. Aurelia, the Warleader (Extra combats)
5. Akroma's Will (Game-ending combat buff)
6. Impact Tremors (Passive damage)
7. Adeline, Resplendent Cathar (Token generator)
8. Skullclamp (Card draw from tokens)
9. Teferi's Protection (Board protection)
10. Blade of Selves (Token duplication)

Attribute Ratings:

Speed: 7/10

• Can threaten lethal via token swarms or Purphoros burn by turns 6-7, accelerated by Isshin doubling triggers.

Resilience: 5/10

• Protection spells and phasing effects help, but reliance on a wide board makes recovery from wipes slow.

Consistency: 7/10

• High density of attack-trigger creatures and token synergies, though limited tutors for key noncreature pieces.

Interaction: 5/10

• Targeted removal (Swords to Plowshares, Rakdos Charm) and combat tricks, but minimal counterspells or stax.

Rating Justification:

This deck operates as a focused aggressive list with T6-8 win potential through combat or burn, aligning with the "Focused" tier (6.0-6.5). While its speed is notable, vulnerability to board wipes and moderate interaction keep it below optimized cEDH levels.

Power level: 6.0 - 6.5
