Not quite in the top 50, my experimenting until I got to this deck cost me quite a few losses because I'm almost always trying to get a better deck. The only decks I personally have trouble with are the firefly/queen/rustler combos and occasionally the poisons if I don't get a decent draw to keep the chrysaora's from using their abilities. I think the aether rare(can't remember what its called) would be a very effective weapon because it allows you to remove the ability of a creature. Since a lot of decks are dependent on creature abilties this could prove a very nice defensive strategy.
