Deck overview

This Dimir deck leverages Marvo, Deep Operative to cheat massive sea monsters directly onto the battlefield. By manipulating the top of the library with cards like Brainstorm, Diabolic Vision, and scry lands, the deck consistently wins clash triggers whenever Marvo attacks. Winning clashes allows the pilot to draw cards and cast spells with mana value 8 or less for free, accelerating game-ending leviathans, krakens, and sagas several turns ahead of curve. The deck reinforces this combat plan with asymmetric board wipes such as Whelming Wave and Scourge of Fleets that clear opposing boards while sparing its own monstrous army. While the deck boasts high card velocity and resilient high-toughness threats, it relies heavily on Marvo surviving to declare attacks and takes several combat phases to fully eliminate three opponents.
