Form [Once per turn]: Ready all cards in your staging area. If you have 3 or fewer characters in your staging area, your Combat Phase ends. If you have 4 or more characters in your staging area, your opponent commits all of their foundations. Playable while committed.

Response Commit: After your opponent makes a check, that check gets -X. X equals the number of characters in your staging area plus 1. Failing this check does not end the Combat Phase.
