I agree in general but coming across that same deathrattle ebola hunter deck 24/7 between rank 5-12 or so, with the exact same 30 cards does get tedious!
Really enjoying gvg so far, though.
The real winners so far seem to be :
Warlock with new viable demon deck cards, and a large boost to giant decks too. The mech zoo stuff is good too.
Mage mech deck seems pretty strong and feels like a murloc deck on steroids a bit. The mechs finally make mage viable again imo, without having to resort to the ice/frosty/secret/duplicate variant of mage! Which was quite horrible!
Paladin...! That weapon that gives you 3 1/1's followed by the boost of 1/1's to 3/3's has justmade them a fair bit stronger now!
Warrior - The cards like shieldmaiden i suspect will be certainly 2 in every single deck, perhaps even losing a shield block to make room.
