Deck overview

This Mardu deck is led by Isshin, Two Heavens as One, who doubles all attacking triggers controlled by the player. The deck capitalizes on this ability by combining aggressive token-producing creatures, extra combat phases, and scaling damage triggers to overwhelm opposing life totals quickly. Mana acceleration in the early turns sets up Isshin on Turn 3, followed by high-impact attack engines such as Adeline, Resplendent Cathar, Otharri, Suns' Glory, and Caesar, Legion's Emperor. As tokens flood the board, permanents like Warleader's Call, Fervent Charge, and Aurelia, the Law Above turn every attack into massive life swings and card advantage. Defensive tools like Dolmen Gate, Boros Charm, and Voice of Victory keep the army safe from combat trades and enemy interaction during crucial turns. The deck also possesses an infinite combat combo via Helm of the Host attached to Aurelia, the Warleader, providing a decisive alternative finish.
