Cards like Biomass Mutation

Biomass Mutation is a unique spell in MTG that brings an interesting dynamic to creature-based strategies. Its closest relative in terms of enhancing creatures is Overwhelming Stampede. This spell also scales the power and toughness of creatures but bases it on the largest creature you control, providing a potential for massive growth. However, Biomass Mutation not only adjusts power and toughness but also allows you to define an exact value for those attributes, granting unprecedented control over the board’s power dynamic.

Another noteworthy comparison is with Strength of the Tajuru, which multiplies counters on creatures. While similar in its scaling potential, Strength of the Tajuru doesn’t offer the same immediate combat surprise that a flash play of Biomass Mutation might. Creature buffs from Biomass Mutation are also not restricted by current counters, again emphasizing flexibility and adaptability during various phases of the game.

Ultimately, Biomass Mutation stands out in the realm of creature enhancement cards. Its ability to set creature attributes regardless of size or counters it makes for a versatile surprise tactic that can dramatically alter the state of the game, particularly in a creature-heavy deck that can capitalize on the sudden shift in power.

Card Pros

Card Advantage: Biomass Mutation shines in decks that focus on quantity of creatures as much as the quality. It has the potential to turn a swarm of modest creatures into game-ending monsters, netting significant card advantage by making every creature a significant threat.

Resource Acceleration: This card doesn’t directly accelerate your resources, but it synergizes well with strategies that do. Cards that ramp your mana allow you to invest more into Biomass Mutation’s X cost, resulting in a larger, more impactful surge in creature power and toughness.

Instant Speed: The beauty of Biomass Mutation is in its versatility thanks to its instant speed. It offers the ability to completely alter combat outcomes unexpectedly, bluff during combat phases, or respond to an opponent’s actions by suddenly boosting your creatures’ size, which can lead to favorable trades or even outright victory.


Card Cons

Discard Requirement: Though not a direct discard requirement, Biomass Mutation demands a significant investment as its effectiveness relies on a substantial mana input. Given its X cost mechanism, it can be cumbersome when your mana pool is limited or when you’re pressured to maintain a defensive stance with potential counterspells.

Specific Mana Cost: The synergy of Biomass Mutation is inherently tied to decks that align with its Simic guild colors (green and blue). This specific mana requirement may deter it from being a staple in decks that cannot reliably generate both types of mana, thus reducing its versatility.

Comparatively High Mana Cost: While Biomass Mutation has the potential to be a game-changing play, its mana value can become burdensome. To make creatures significantly larger, a hefty mana investment is needed which might be better utilized on building board presence or other control elements, especially in fast-paced games where efficiency is key.


Reasons to Include in Your Collection

Versatility: Biomass Mutation offers the unique ability to surprise opponents with an army of unexpected massive creatures. This card can seamlessly adapt to a range of situations, making it a valuable asset in decks that aim for sudden, game-winning strikes.

Combo Potential: This card works wonders in synergy with deck strategies revolving around creature numbers, such as token decks, by transforming a wide board into lethal attackers regardless of their original power and toughness.

Meta-Relevance: In a meta where board states can be cluttered with creatures, Biomass Mutation provides a way to turn the tide of battle, potentially bypassing stalemates and dominating combat in what could be a critical turn.


How to beat

Biomass Mutation is a unique card within the Magic: The Gathering realm, often turning an unassuming horde of creatures into a lethal army in mere moments. Its power resides in its ability to make the creature’s size match the mana invested into the spell. To effectively counter this green-blue instant, one approach is to use removal spells that clear the board before the Mutation’s effects can manifest. Cards like Wrath of God or Damnation can be game-changers against it.

Alternatively, permission spells such as Counterspell or Negate offer a direct solution by preventing Biomass Mutation from resolving in the first place. Hand disruption tactics, including Thoughtseize or Inquisition of Kozilek, can disrupt your opponent’s plan by removing the card from their hand before they have a chance to cast it. Timing is critical – keeping mana open for counters or swiftly slashing at an opponent’s creature base can ensure that Biomass Mutation never has the opportunity to alter the tide of battle.

The key to overcoming this spell lies in anticipation and disruption. Knowing when to dismantle an opponent’s strategy before it unfolds makes all the difference in coming out on top against Biomass Mutation’s potential for a surprise victory.

Rules and information

The reference guide for Magic: The Gathering Biomass Mutation card rulings provides official rulings, any errata issued, as well as a record of all the functional modifications that have occurred.

Date Text
2013-01-24 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).
2013-01-24 Choosing 0 as the value for X will likely cause creatures you control to become 0/0 and be put into the graveyard.
