Isshin

Isshin is a Mardu (red/white/black) aggro-combat commander deck built around Isshin, Two Heavens as One, which doubles attack-triggered abilities. The deck aims to go wide with tokens and value attackers, then overwhelm opponents through stacked combat triggers, extra combat steps, and incidental damage.

Key synergies include:

• Attack-trigger payoffs doubled by Isshin: cards like Adeline, Hero of Bladehold, Hanweir Garrison, Krenko, Anim Pakal, Otharri, Etali, and Captain Lannery Storm generate extra tokens, mana, or value.
• Extra combats from Aurelia, Karlach, Raiyuu, and Combat Celebrant let those triggers happen again and can quickly snowball into lethal damage.
• Go-wide burn finishers like Purphoros, God of the Forge, Impact Tremors, and Brutal Hordechief convert token swarms into direct damage and hard-to-block alpha strikes.
• Strong protection and interaction with **Teferi’s Protection, Clever Concealment, Flaw
