Crystal Beast Cobalt Eagle (DP07-EN006) - Duelist Pack 7: Jesse Anderson 1st Edition

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.
