Consuming Ashes
Instant
Exile target creature. If it had mana value 3 or less, surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)
The enforcer only got halfway through the arrest warrant before it—and he—went up in smoke.

If the target creature is an illegal target as Consuming Ashes tries to resolve, it won’t resolve and none of its effects will happen. You won’t surveil.
