Clerical Error?

[Ughihadtoregistertopost]

So I have the original munchkin and I was just wondering if this situation is fair:
My friend gets the cleric class and when ever someone plays a "go up a level" "duck of doom" or "Devine intervention" cards he resurrects them regardless of whose turn it is and uses them and ressurects them again and again until he wins and we are all level one. However, he does only resurrect one item per turn like it says on the card but this is annoyingly foolproof unless we discard on top of the card he wants. Also, he discards and picks it up before anyone knows what happened catching us all off guard. Is there some kind of rule for how he can announce it so we have time to react?
