Hazora, the Unity

Indestructible, hexproof from monocolored

Whenever you cast a spell that is more than one color, splinter target non-token creature you control.

(When a creature splinters, exile it. Divide its power and toughness by two rounded up, and make two tokens of it. When both tokens perish, return the exiled card to the battlefield.)
