Goblin Biker Grand Crisis

You can target 1 "Goblin" monster you control and 1 monster your opponent controls, or target 1 "Goblin" monster in your GY and 1 monster in your opponent's GY; banish both monsters. You can send this face-up card from the Spell & Trap Zone to the GY, then target 5 of your banished "Goblin" monsters with different names; Special Summon them. You can only use 1 "Goblin Biker Grand Crisis" effect per turn, and only once that turn.
