The Ruinous Powers (Warhammer 40,000 Commander Precon Decklist) by Lead_Brick

Format: Commander

Commander: Abaddon the Despoiler

Bracket: 2

Deck overview

Abaddon the Despoiler leads a Grixis Demon cascade value deck that turns early life loss into free spells. You deal damage with Abaddon and other attackers to raise the cascade limit, then cast Demons and removal that cascade into additional threats. Be'lakor, Warstorm Surge, and Keeper of Secrets convert each Demon entry into direct damage and cards, while Magnus the Red and Herald of Slaanesh reduce costs and give haste. Secondary lines use extra combats from Bloodthirster and token generation from Mortarion and Great Unclean One to close through combat. The deck has no infinite combo and wins by accumulating board presence and burn triggers over several turns, with Past in Flames and cascade enablers providing late-game refills.
