Advanced Crystal Beast Cobalt Eagle

This card's name is also treated as "Crystal Beast Cobalt Eagle". If this card is on the field but "Advanced Dark" is not on the field, destroy this card. Once per turn, you can return 1 face-up "Crystal Beast" card you control to the top of its owner's Deck. If this card is destroyed while it is in a Monster Card Zone, you can place it face-up in your Spell & Trap Card Zone as a Continuous Spell Card, instead of sending it to the Graveyard.
