The Locust God + Tymora's Invoker + Ashnod's Altar + Queen Allenal of Ruadach

The Locust God

Tymora's Invoker

Ashnod's Altar

Queen Allenal of Ruadach

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 and two 1/1 Soldier creature tokens.
3. Activate Ashnod's Altar four times by sacrificing the Insects and Soldiers, adding eight C.
4. Repeat.

This engine starts by activating Tymora's Invoker, whose hefty mana ability draws you two cards to kick off The Locust God's triggered ability. Every time you draw, The Locust God floods the board with flying Insects, which Queen Allenal of Ruadach then supersizes by tagging an extra Soldier onto every single creation event. You then feed those freshly minted bodies right into Ashnod's Altar, converting your swarming token army into the exact colorless mana needed to fund Tymora's Invoker's next activation and keep the loop spinning infinitely.
