Deck overview

This Rakdos deck is built around Grenzo, Dungeon Warden and maximizes creature density to cheat permanents directly from the bottom of the library into play. By keeping creature power low, almost every creature in the 99 can enter the battlefield off a Grenzo activation. The deck uses enter-the-battlefield land searchers and ritual creatures to accelerate mana without diluting creature slots. It leverages sacrifice outlets, graveyard-to-library recyclers, and damage pingers to grind incremental advantage before executing a decisive finish. The primary win condition is an infinite mana loop using Workhorse and The Cauldron of Eternity alongside Grenzo. Once infinite mana is generated, the entire library is deployed onto the battlefield, and pingers like Molten Gatekeeper and Witty Roastmaster eliminate all opponents simultaneously.
