Knockout Maneuver
Sorcery
Put a +1/+1 counter on target creature you control, then it deals damage equal to its power to target creature an opponent controls.
Rulings
- You can't cast Knockout Maneuver unless you choose a creature you control and a creature an opponent controls as targets.
- If either creature is an illegal target as Knockout Maneuver resolves, the creature you control won't deal damage. If the creature you control is an illegal target, you won't put a +1/+1 counter on it even if it's still on the battlefield.
