Lots of flexibility with this build.
Wincon:
1. Hemet, Mecha’Thun, Floop + Starfall (with nothing left in deck or on board)
2. Mecha’Thun, Innervate, Naturalize (with nothing left in deck or on board)
3. Floop after playing Mecha’Thun + charged Spellstone
Strategy:
1. Ramp – wild growth in mulligan and try to nourish for mana on t5
2. Cycle – If you can’t find Hemet, you can cycle through your deck extremely quickly with Gadgetzan Auctioneer
3. Board Clear – Wild Pyro can do 5 damage easily in combination with Barkskin. Floop can be a 3rd Pyro.
4. Setup Mecha’Thun wincon with remaining resources
