From Wilds of Eldraine set
Rat Out
Instant
Up to one target creature gets -1/-1 until end of turn. You create a 1/1 black Rat creature token with "This token can't block."
Rulings
- You can cast Rat Out without a target just to create a Rat token. However, if you do choose a target, and that target is illegal at the time Rat Out tries to resolve, the spell won't resolve and none of its effects will happen. You won't create a Rat token.
