Starts with Zeus, Luna and Venom because of their good skills for turn 1. Survive the first turns by using Frostbite, Cunning Plan, Ventriloquy (+ Relentless Zombie) and Compel.
Once you have access to Eclipse and Thundergod's Wrath, use them to take over the boards, and while controlling waves with Sow Venom, Ignite, Zeus' passive, Luna's passive, Tower barrage, Remote Detonation and Dimensional Portal. Meanwhile, try to get as many Foresight and Aghanim's Sanctum as possible.
Close the game by using Red Mist Maul and Dimensional Portals against open boards, and Bolt of Democles.
Some extra control to survive the early stages comes with Buying Time, Fractured Timeline and Clauzreme Hourglass.
