The battle plan is to kill your opponent with the creatures you give them.

Forbidden Orchard, Hunted Phantasm and Varchild's War-Riders give your opponent a bunch of tiny creatures.

Blood Artist and Dingus Staff punish your opponent harshly when those creatures die.

Pyroclasm, Illness in the Ranks and Noxious Field kill those creatures off for you.

Tainted Aether forces your opponent to sacrifice when you give them creatures, and if you can kill the creatures in response, they'll have to sacrifice a bunch of their own creatures.
