I love how Quest Taunt C'Thun Warrior (without the C'Thun) was a thing in Global Games and it won a game!
It feels like the meta keep shifting depending on what the best deck is; last week VS Reaper had Quest Rogue as a really strong deck. Then players adjusted and suddenly Freeze Mage is top dog. I remember when midrange Murloc Paladin felt oppressive, then the crabs / mages came out. I like the dynamic feel of the meta and we'll see what decks are hiding out because Quest Rogue exists.
I'm skeptical we'll see another top tier deck (last one I think was Evolve/Devolve Token Shaman), but I'm sure we'll find some really cool tier 2-3 decks in the last month of Un'goro.
