When I saw Lunar Claw at the first time, I wanted to try it in Combrei Relic deck. It fits good on 3-rd slot instead of old Enter the Monastery and gives another way for not lose to aggro or effectively block useful card in opponent's hand. 4 cost Enter the Monastery is here too - game is more slow now, but it ramps good. Deck is based on spiffirific's LCQ and has 64% winrate atm.
