Card Details
Mana CostSet
Character Background
Biomass Mutation is a clean, explosive pump spell for go-wide green-blue decks, especially token swarms and tempo builds that want to turn a modest board into an immediate threat. Because it sets base power and toughness to X/X until end of turn, it doesn’t just add counters—it overwrites the stat line, making even tiny creatures suddenly formidable and helping you dodge some effects that care about printed size. The card shines when you can flood the battlefield first, then spend your mana at the end of the opponent’s turn or before combat to threaten a lethal swing. It also pairs well with creature tokens, evasive bodies, and any strategy that can generate large amounts of mana, such as ramp or untap synergies, letting X scale into a true finisher. In gameplay terms, it rewards patience and board presence, converting accumulated biomass into one decisive, overwhelming mutation.
