Crystal Beast Cobalt Eagle (FOTB-EN006) [Force of the Breaker]

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.
