Malign Intervention

[MunchkinMan]

A Curse will always have Curse in the name. "Usable once only" only needs to appear on Items, since most Items remain in play while being used. If a card doesn't conform to one of the types of cards that remain in play, then it follows a very basic rule: Put it in your hand when you draw it, play it whenever you want (or when the card says), resolve its effect(s), then discard it.
