During the Standby Phase of the next turn after this card was banished: You can Special Summon this banished card. During your opponent's Main Phase, if this card was Special Summoned this turn, you can (Quick Effect): Immediately after this effect resolves, Synchro Summon 1 Fish Synchro Monster using this card you control. You can only use each effect of "Shif, Fairy of the Ghoti" once per turn.
