Adapting Lizard

Mutate {1}{u}{r} (If you cast this spell for its mutate
cost, put it over or under target non-Human creature
you own. They mutate into the creature on top plus all
abilities from under it.)
Whenever you cast an instant or sorcery spell,
you may instead put that card over Adapting
Lizard. If you do, Adapting Lizard gains
"{3}{u}{r}, {t}: Activate the ability of target
non-permanent spell on Adapting Lizard."
