■ When this card enters the field, you may drop a hand card. If you do, put up to one [Heathcliff] or "Huge Floating Castle, Aincrad" from your deck into your hand, and shuffle your deck.

■ If this card is in the soul of a [Heathcliff], that card cannot be destroyed or returned to hand and its souls cannot be dropped by your opponent's card effects.
