It is a legitimate tactic. It doesn't always work. You may not turn one over or you may have one in your hand and get a monster when you kick down the door. Or you may not be able to keep it in your hand or others may be able to hold onto cards that prevent you winning. The other tactic is make it difficult for them to get to level 9 in the first place if possible. Recently I have started playing nasty cards at level 6 or 7 especially if bad stuff is nasty. If they are holding onto cards to help them win they will have to use them then and not have much when at higher level. So it is all about adapting and finding different ways to mess with people.
