"Find me cards equivalent to: Biomass Mutation"

Cards similar to Biomass Mutation (instant, GU, boosts creatures to X/X) are rare. The closest are:
1. Overwhelming Stampede (Green, Sorcery, not instant; gives creatures +X/+X).
2. Coat of Arms (Artifact; static effect, not an instant).
3. Kamahl's Will (Green, Instant; can turn lands into 1/1s for turn).
4. Solidarity of Heroes (Green, Instant; doubles +1/+1 counters, not exactly X/X).
5. Curiosity Crafter (U, creature, no such effect).

None match perfectly—the instant X/X effect is nearly unique to Biomass Mutation. Consider using Overwhelming Stampede for a similar board-wide boost, though slower.

  • Biomass 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.

  • If a creature has more than one creature type, and one of those types matches the creature you are calculating for, then count that creature. Only one type needs to match in order to get counted.
  • If you have a creature with more than one creature type, count all creatures which have either creature type.
  • Sharing multiple creature types doesn't give an additional bonus. Coat of Arms counts creatures, not creature types.

  • A land that becomes a creature because of the first mode will retain any other supertypes, card types, subtypes, and abilities it had.
  • Even though the card is named after a specific character, controlling any commander will satisfy its condition.
  • If some but not all of the targets become illegal, Kamahl's Will will resolve but have no effect on illegal targets. If the target of the second mode becomes illegal, no damage will be dealt.
  • If you choose both modes, the effects happen in the listed order. The lands will become 1/1 creatures in time to deal damage to the target of the second mode.
  • Once you've announced that you're casting a spell, players can't take any actions until you've finished doing so. Notably, opponents can't try to remove your commander to change how many modes you may choose.
  • Once you've chosen both modes for the spell, it doesn't matter whether you continue to control a commander. This is true even if you somehow no longer control a commander as you finish casting the spell.
  • The commander you control doesn't have to be your commander.
  • There's no extra bonus if you control more than one commander.

    Choose one. If you control a commander as you cast this spell, you may choose both instead. • Until end of turn, any number of target lands you control become 1/1 Elemental creatures with vigilance, indestructible, and haste. They're still lands. • Choose target creature you don't control. Each creature you control deals damage equal to its power to that creature.

    Rules

  • If a spell or ability allows you to cast a strive spell without paying its mana cost, you must pay the additional costs for any targets beyond the first.
  • If all of the spell's targets are illegal when the spell tries to resolve, it won't resolve and none of its effects will happen. If one or more of its targets are legal when it tries to resolve, the spell will resolve and affect only those legal targets. It will have no effect on any illegal targets.
  • If such a spell is copied, and the effect that copies the spell allows a player to choose new targets for the copy, the number of targets can't be changed. The player may change any number of the targets, including all of them or none of them. If, for one of the targets, the player can't choose a new legal target, then it remains unchanged (even if the current target is illegal).
  • Solidarity of Heroes can target any creatures, not just ones with +1/+1 counters on them. Notably, heroic abilities of any target creatures that put +1/+1 counters on that creature will resolve before Solidarity of Heroes.
  • The mana cost and mana value of strive spells don't change no matter how many targets they have. Strive abilities affect only what you pay.
  • You choose how many targets each spell with a strive ability has and what those targets are as you cast it. It's legal to cast such a spell with no targets, although this is rarely a good idea. You can't choose the same target more than once for a single strive spell.

    Strive — This spell costs more to cast for each target beyond the first. Choose any number of target creatures. Double the number of +1/+1 counters on each of them.
