Overview:

This Mardu attack-trigger deck leverages Isshin, Two Heavens as One to double combat-related abilities, focusing on token generation, extra combats, and damage amplification. It combines efficient creature-based value engines with a potent infinite combat combo, supported by strong tutors and protection.

Primer:

Core Strategy:
The deck aims to overwhelm opponents through doubled attack triggers, using token generators (Myrel, Shield of Argive, Adeline, Resplendent Cathar) and damage amplifiers (Hellrider, Tectonic Giant). The primary wincon is the infinite combat loop of Aggravated Assault + Sword of Feast and Famine, enabled by Isshin’s trigger duplication. Secondary lines involve overwhelming board states with tokens and value engines like Purphoros, Bronze-Blooded and Goldspan Dragon.

Key Phases:

1. Setup (Turns 1-4): Deploy mana rocks (Sol Ring, Arcane Signet), tutors (Vampiric Tutor, Enlightened Tutor), and early attackers like Aethergeode Miner.
2. Explosion (Turns 5-7): Cast Isshin and attack with enablers like Hanweir Garrison (creating 4 tokens per swing) or Aurelia, the Warleader for extra combat phases.
3. Finishers: Resolve infinite combats via Aggravated Assault/Sword synergy or flood the board with tokens boosted by Akroma's Will or Rising of the Day.

Mulligan Priorities:

• Keep hands with 3 lands, early ramp, and at least one attack-trigger creature.
• Prioritize hands with combo pieces or tutors in slower metas.

Key Tips:

• Use Reconnaissance to safely trigger attack abilities without losing creatures.
• Smothering Tithe funds Aggravated Assault activations.
• Protect Isshin with Lightning Greaves and Flawless Maneuver.

Avoid Traps:

• Overextending into board wipes without protection.
• Holding combo pieces without tutors to assemble them.

Weaknesses:

Critical:

• Relies on Isshin for trigger doubling; 3+ removals cripples the deck.
• No graveyard recursion for key creatures.

Moderate:

• Limited interaction against noncreature permanents.
• Vulnerable to stax effects like Ghostly Prison or Cursed Totem.

Minor:

• Tapped lands slightly slow early setups.

Most Important Cards:

• Aggravated Assault
• Sword of Feast and Famine
• Aurelia, the Warleader
• Myrel, Shield of Argive
• Purphoros, Bronze-Blooded
• Smothering Tithe
• Vampiric Tutor
• Enlightened Tutor
• Akroma's Will
• Adeline, Resplendent Cathar

Attribute Ratings:

Speed: 7/10

• Infinite combat combo can win as early as T5 with perfect draws. Typical explosive turns occur T6-7.

Resilience: 6/10

• Multiple protection spells (Boros Charm, Flawless Maneuver) but folds to repeated Isshin removal. Token generators provide backup value.

Consistency: 7/10

• 7 tutors (including Grim Tutor, Imperial Recruiter) and strong draw (Necropotence, Painful Truths). Redundant attack-trigger creatures.

Interaction: 5/10

• Efficient targeted removal (Swords to Plowshares, Chaos Warp) but lacks counterspells. Board wipes (Ruinous Ultimatum) are high-impact but slow.

Rating Justification:

This deck sits between "Optimized" (6.5) and "Focused Competitive" (7.0) on the rubric. Its combo potential and tutor density rival lower-tier cEDH decks, but its reliance on combat and vulnerability to interaction place it just below tuned stax/storm lists. The T5-7 win window and robust redundancy justify a high-power casual rating.

Power level: 6.5 - 7.0
