Crippling Fear - mtg.wtf

2021-02-05 Crippling Fear affects only creatures that aren't of the chosen type that are on the battlefield as it resolves. It won't affect creatures that enter the battlefield later in the turn, regardless of creature type. If a creature changes creature types later in the turn, Crippling Fear won't start or stop affecting that creature.
