Excise the Imperfect
From March of the Machine Commander set
Excise the Imperfect
Instant
Exile target nonland permanent. Its controller incubates X, where X is its mana value. (They create an Incubator token with X +1/+1 counters on it and " : Transform this token." It transforms into a 0/0 Phyrexian artifact creature.)
Rulings
- If the nonland permanent is an illegal target at the time Excise the Imperfect tries to resolve, it won't resolve and none of its effects will happen. Its controller won't incubate.
