2 Level 8 monsters During each player's turn, you can banish 1 face-down monster from your opponent's Extra Deck at random, and if you do, this card's ATK becomes equal to that of the banished monster. During each player's turn, you can detach 1 Xyz Material from this card, then target 1 of your opponent's banished Fusion, Synchro, or Xyz Monsters, return it to the Extra Deck, and if you do, destroy 1 monster your opponent controls of the same Monster Type (Fusion, Synchro, or Xyz). You can only use each effect of "Aegaion, Castle of the Seas" once per turn.
