Unexpected Strike
Event - End all ongoing effects of one Event that has already resolved.
If the event has both (an) ongoing effect and an effect that is not considered an ongoing effect (for example, Shattered Focus), does Unexpected Strike just end the ongoing effect, and leave the rest of the event in play?
