Deck overview

This deck is a high-power Dimir control and combo build centered around Toxrill, the Corrosive. It leverages powerful mana acceleration (Chrome Mox, Mana Vault, Dark Ritual) and top-tier tutors (Demonic Tutor, Vampiric Tutor) to deploy oppressive creature suppression and assemble instant-speed win conditions. The primary win condition utilizes a self-sustaining -1/-1 counter loop between Blowfly Infestation and Nest of Scarabs, paired with aristocrat drain pieces like Blood Artist, Zulaport Cutthroat, or Mirkwood Bats to drain the entire table in a single turn. Defensively, the deck protects its combo and board state with a robust suite of free and efficient counterspells (Force of Will, Fierce Guardianship, Pact of Negation). As an alternate path to victory, the deck can establish an asymmetric lockout by combining Kormus Bell and Urborg, Tomb of Yawgmoth with Toxrill or Maha, Its Feathers Night, turning all opposing lands into 1/1 creatures that are wiped at the end of every turn.
