Utopia Island

Enchant island
Whenever enchanted island is tapped, Mutant spells you cast have convoke. (Your creatures can help cast those spells. Each creature you tap while casting an mutant spell pays for {1} or one mana of that creature's color.)
Here on Utopia Island, there are no rules. There's no government, no baby sitters, no bedtimes, only mutants helping mutants come out of the shadows.
