The Action card Battle of the Titans says that if any of the named Olympians are missing, “all except Zeus must be discarded.” Does that mean all of those named, or all Keepers in play?

A: Only the named Olympians are discarded (except for Zeus). They are the ones who participated in war between the Titans and the Olympians, so they are the only ones affected: basically, if the whole team isn’t there, they lose the battle. Other Keepers in play are not affected.
