Mulligans
An Otk with Ultrasaur, Windfury and Crazed Alchemist or Kooky Chemist. Against aggro mulligan and use board-clears and Hallazeal the Ascended to stall and heal, against control use Ancestral Spirit with big taunts to bait out hard removal. For the combo if your opponent still has removal use Emperor Thaurissan and Ancestral Spirit on your Ultrasaur.
