The Locust God + Tymora's Invoker + Ashnod's Altar + Primal Vigor

The Locust God

Tymora's Invoker

Ashnod's Altar

Primal Vigor

How it works

1. Activate Tymora's Invoker by paying 8, causing you to draw two cards.
2. The Locust God triggers twice, creating four 1/1 Insect creature tokens with flying and haste.
3. Activate Ashnod's Altar four times by sacrificing the Insects, adding eight C.
4. Repeat.

By pumping massive amounts of mana into Tymora's Invoker, you crack open the draw engine that fuels the entire operation. Each card drawn triggers The Locust God, which fills your board with Insect tokens while Primal Vigor doubles their numbers to ensure you always have enough fodder. You can then feed those newly created tokens directly into Ashnod's Altar to generate the exact colorless mana needed to activate Tymora's Invoker once more, keeping the loop spinning endlessly.
