This spell costs less to cast if it targets a Dinosaur you control.
Put a +1/+1 counter on target creature you control. Then that creature fights target creature you don't control. (Each deals damage equal to its power to the other.)
Wayne Reynolds INTERVIEW
You canâ€™t cast Savage Stomp unless you choose both a creature you control and a creature you donâ€™t control as targets.
If the creature you control is an illegal target as Savage Stomp tries to resolve, you wonâ€™t put a +1/+1 counter on it. If that creature is a legal target but the other creature isnâ€™t, youâ€™ll still put the counter on the creature you control.
If either target is an illegal target as Savage Stomp resolves, neither creature will deal or be dealt damage.
