Try to damage yourself in the early game while also keeping cards in hand so you can play Mountain Giant followed by Flesh Giant. Mojomaster Zihi is good for matchups where the opponent has a combo (mostly Reno Priest, Quest Mage and most Druids) or just really great late game value (Cubelock or Dead Man’s Hand Warrior).
This deck is oddly good against aggro, because you can clear early threats and outscale them with your giants, Rogues in special have a hard time dealing with your board. The worst matchups would be Reno Priest, Quest Mage, Big Shaman and Pirate Warrior because of the cannons’ RNG.
