The OTK is as follows:

Play Celestial Alignment.

Reach 4 mana.

Play some combination of Oracle of Elune, Germination and Humongous Owl so that you have 4 owls on board.

Play Deathwing the Destroyer to clear the board and throw 32 damage into your enemy's face.

Maybe I missed it, but I feel like I haven't seen anyone abusing Oracle of Elune with Celestial Alignment. She WILL copy ANY minion whose cost is set to 1 (including another Oracle of Elune). I'm sure there are lots of cool things to do with that.

This deck plays just like most other Celestial decks: ramp, stall, gain armor, prepare your combo.

Comments and suggestions welcome!
