Rapier Wit
Instant
Tap target creature. If it's your turn, put a stun counter on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)
Draw a card.
Rulings
- If the target creature is an illegal target as Rapier Wit tries to resolve, it won't resolve and none of its effects will happen. You won't draw a card.
