Mutant

Mutants are altered beings by unnatural factors whether magical or biological origin. They can theoretically be found on any plane. The first cards to bear the creature type was Mistform Mutant in Onslaught, though the Goblin Mutant from Ice Age was later issued errata to become a Mutant as well. Mutants appear in all colors. They mainly appeared in Onslaught block and Dissension

Alara

Grixis Mutants

On the Shard of Alara known as Grixis, "stale" magical energy mutated some of its denizens. Most notable are the race of Ogres known as the Incurable.

Dominaria

Otarian Mutants

The barbarian turned druid, Kamahl, resided in the Otarian forest of Krosa, and it was he who planted the Mirari there thinking that without a wielder the artifact would be harmless. However its power was soaked into the entire continent and the radiation mutated the inhabitants, especially those within the forest, transforming many of the beasts into enormous in fiercer and stronger monsters. This caused the animals of the forest to go mad, wildly attacking anyone that entered the forest and even leaving the forest to attack surrounding farmsteads and villages.

As the Mirari's magic washed across Otaria, many aven became taller and more muscular, with long, razor-like talons jutting from their wings. The most advanced of these mutants lost their arms, regressing into huge sentient raptors.

On the other hand, mutant owl aven, known as crookclaws, also grew larger and sprouted talons from their wings, but retained independent use of their arms (Crookclaw Transmuter). The crookclaws' magical abilities were also enhanced by the Mirari's emanations.

Ravnican Mutants

Simic

Biomancers (genetic biologists affiliated with the Simic Combine) were responsible for the mutants of Ravnica in their attempts to improve the life forms of that plane. Most members of the Simic Combine even alter themselves purposedly, becoming mutants to enhance their abilities. One such technique used the cytoplast implants which, within the game, is represented with the Graft ability.

With the decline of Momir Vig's influence and the resurgence of the Combine, a new form of mutation has taken root. A mix of two races, called a krasis. The experiments progressed so far that sometimes the original breed isn't recognizable anymore (Simic Manipulator).

Innistradi Mutants

The Civilized Scholar is a Homicidal Brute by night.

Emrakul

The Eldrazi Titan Emrakul warps and corrupts biological life mutating it into her spawn. Though such creatures do not have the Mutant type on the cards (instead being horrors or eldrazi), they are referred to as "mutants" in various supplemental material.

Trivia

• 12 Mutants appeared in Legions, 7 in Scourge, and 13 in Dissension.
• Mutations can be caused by spells like Transmutation, Darksteel Mutation, Grotesque Mutation, Unstable Mutation, Mutagenic Growth and Fatal Mutation. Those spells, sadly, do not confer the Mutant subtype.
