Mutagen tokens are a kind of predefined token. Each one is a colorless artifact with the artifact subtype Mutagen and the ability "
, , Sacrifice this token: Put a +1/+1 counter on target creature. Activate only as a sorcery." - WotCJan 27, 2026
Some spells and abilities that create Mutagen tokens require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. The Mutagen token won't be created.
