Clear and play taunts.
Ramp up into Hadronox and great taunts like Witchwood Grizzly or Rotten Applebaum. You can save Witching Hour and your beast taunt minions to bring back Hadronox for 3 mana and then bring back even more Appletrees.
I am thinking of variants of taunt deck with hadronox, but problem with your deck is lack of silence for warlock cubes or Rin.
All right. What should be replaced for a spellbreaker?
