Honestly, I just created the standard GVG Antonidas deck (basically, you control the board and create spare parts, then drop Antonidas, use spare parts to protect him, and accumulate fireballs), and off I went. I'm at the low end of Rank 6 now though, because of the damn hunter rush decks. During my climb up the ranks I saw a lot of control warrior and zoo warlock, as well as other Atonidas Mage decks and an occasional Rogue deck, but over the past 2 days I feel like I'm seeing Hunter rush decks 3 out of every 5 games. It's absurd.
Seriously, I don't know how to beat them. They use a lot of deathrattle beasts that help them control board when they're not pounding your face (haunted creeper, the deathrattle lion), the eaglehorn bow, lots of secrets, and kill commands to finish you off.
Usually I can gain control of the board by turn 4 or 5, but by then my Mage is down to 14 or so health. The Hunter hero ability just keeps chipping away, and once a kill command comes up, I'm toast.
I'm kind of thinking a really good Priest deck could take advantage of the meta right now. Lots of silence and/or cabal shadow priest to take care of annoyances like haunted creepers. Healing ability helps combat Hunter hero ability. Maybe also use one of those new GVG secret stealer minions in the deck.
Thoughts?
