Deck overview

This deck is a high-powered Mono-Black competitive combo strategy designed to assemble fast, decisive game wins. Leveraging format-ceiling fast mana rocks like Mana Vault, Chrome Mox, and Lion's Eye Diamond alongside powerful black rituals, the deck accelerates into explosive card engines such as Ad Nauseam, Peer into the Abyss, and Necropotence. The primary victory path pairs Professor Onyx with Chain of Smog, looping self-targeted copies to trigger Magecraft and drain all three opponents to zero in a single turn. Redundant lines include reanimating Razaketh, the Foulblooded to tutor infinite chains, the classic Mikaeus, the Unhallowed and Triskelion damage loop, and storming with Bolas's Citadel, Sensei's Divining Top, and Aetherflux Reservoir. Formidable stax pieces like Contamination, Opposition Agent, and Dauthi Voidwalker proactively disrupt opponents while the deck prepares its win.
