This Sultai (B/G/U) deck revolves around the mutate mechanic with Otrimi, the Ever-Playful as the commander, aiming to stack abilities on a single resilient creature. The primary strategy involves mutating creatures like Auspicious Starrix and Sawtusk Demolisher onto a base creature to generate value, removal, and board presence. Otrimi enables graveyard recursion of mutate creatures, while secondary themes include +1/+1 counters, combat tricks, and midrange value via cards like Zaxara, the Exemplary and Villainous Wealth. The deck wins through combat damage with a mutated threat or incremental value from life drain (Insatiable Hemophage) and stolen resources.
