Bloodmage > Ysera > TBK for control. 

Yeah old school rogue has always done well vs this.deck. It's about 75/25, which is pretty good. Shamans also have a slightly favorable matchup, although it's more like 60/40. Reynad also came out with a paladin control deck on his youtube channel, and he mentioned it's does decent vs board control lock because the zoo deck was designed to play around Druids and swipe.

The game has been in beta for a while now. Even just doing 1 arena/day without spending any money I've opened upwards of 130 packs.

Please tell me you've one shot someone with Velen + Coin + Double Mind Blast.

Thalanos is really poor with priests, it only synergizes with Holy Nova. I know you're picking it because it cycles, but it's absolutely useless after your drakes/giants are out.

I run a similar build with Drakes, but I run Sunfury Protectors/Argus/Watcher/Spellbreaker to help vs aggro and hunteres.

You said Thalanos twice, did you mean something else? If you run control, Black Knight is excellent.

I have Hogger and he is pretty subpar. At 6 mana, unless you're already massively ahead, he can win you the game barring he doesn't have any AoE. But the catch is you won't be that far ahead by turn 6 unless you're running an aggro, and if you are, then he's way too slow for an aggro deck. A better solution to aggro is actually Geddon.

For control:
1) Black Knight
2) Ysera
3) Cairne (big drop between this and Ysera unless you are playing pally with Redemption)
4) Geddon (possibly #3, him and Cairne are close)

For aggro:
1) Leeroy
2) Black Knight
