To the Eyrie is a terrible card. I'm sure I'm preaching to the choir here, but just look at it. It's eerie how bad this is. You pay two resources (not inexpensive) and exhaust an eagle (don't want to do that) just to return a dead ally to hand (as opposed to back into play). I suppose some corner-case scenario could be found where this is remotely useful, but this is just plain bad.
To the Eyrie
Event. Cost: 2.
Response: After an ally is destroyed, exhaust 1 Eagle character to move that ally from the discard pile to its owner's hand.
