The Combo:
Play High Priest Amet and then use Divine Spirit on him x2, follow this up by x2 Stonetusk Boar and x2 Topsy Turvy fo 56 damage.
Alternate Strats
The nice part about this deck is its flexibility. If for some reason your combo is disrupted, that’s ok, there are still other ways to win. Most notably is Chef Nomi. your deck is designed to cycle very fast so getting his effect should be very easy. Once you play him you can cast Seance on him. This allows him to be played multiple times.
When up against an aggressive deck it can be very hard to pull off your combo or Nomi fast enough. That is what Grave Horror is for. Because you play a lot of cheap spells he will cost nothing very soon, combo a cheap Grave Horror with Seance and it normally is too much for the aggressive deck to deal with.
Otherwise, the game plan is to cycle through your deck as fast as possible using Gadgetzan Auctioneer and control the board via Wild Pyromancer and Mass Hysteria in hopes that you can pull out a win before your opponent draws Mountain Giant into Conjurer's Calling.
Good Luck!
I like the concept. I build a similar wich is more based in drawing cards 🙂
