The player with this card saved may control all Psi cards used by any opponents. If the player denies the use of a Run Psi card to an opponent, then the opponent must discard it. If the player denies the use of a saved Special or Very Special Psi card to an opponent, then the opponent may keep the card and try again on his next turn.
If Psi Corps is used for a Psi card play (Non-Matching Colors), then a player may use the card immediately or save the card directly from his five-card hand if he has at least one bunny in The Bunny Circle.
If at any time the player has no bunnies in The Bunny Circle, then Psi Corps is discarded immediately. Players cannot save this Special without a bunny in The Bunny Circle.
