Prices are the latest nightly market price; a printing with no tracked price shows a dash. Dealer buylist is Card Kingdom's current offer via MTGJSON, shown where one exists.
Legality is a property of the card, not the printing, so it is identical for all 10 versions.
Official Judge Precedents
2 PrecedentsBiomass Mutation overwrites any effects that set the power and/or toughness of a creature you control to a specific value. Effects that modify power and/or toughness but don't set them to a specific value (like the one created by Giant Growth), power/toughness changes from counters, and effects that switch a creature's power and toughness will continue to apply. For example, say you control a 1/1 creature that's getting +4/+2 from an Aura, has a +1/+1 counter on it, and is affected by an effect that switches its power and toughness. This creature is 4/6. If you cast Biomass Mutation with X equal to 4, the creature would become 7/9 (4/4, +4/+2 from the Aura, +1/+1 from the counter, then switch power and toughness).
Choosing 0 as the value for X will likely cause creatures you control to become 0/0 and be put into the graveyard.
