原文If you don't control a creature with power 4 or greater as your end step begins, Furious Rise's ability doesn't trigger. If you don't control one as the ability resolves, it has no effect. It doesn't have to be the same creature at both times, however.
原文Furious Rise's effect doesn't change when you can play the exiled card. For example, if you exile a sorcery card, you can cast it only during your main phase when the stack is empty. If you exile a land card, you can't play it unless you have land plays available.
