Start off with Gahz’rooki and use Bite twice and then Geyser. Bring in Chrominius whether or not Gahz’rooki dies. Cast Howl when Geyser only has 2 rounds left and Bite, Bite, Bite. Zao should be dead. The Custodian can finish things off if you need with Ion Cannon.
Use the Foxling first because he’s your setup pet. Use Dazzling Dance, then Bite, and then Howl. Don’t use Bite if Xu-Fu critically hit you on the first turn. Do your best to make sure Howl is used on the turn the Foxling will die. Bring the Spider in and use Brittle Webbing and then Spiderling Swarm. This should pretty much take care of him, but if it doesn’t you can bring in the Custodian and Zap or Ion Cannon Xu-Fu into the ground.
