Resolve the first ability, causing you to draw two cards.
The Locust God triggers twice, creating two 1/1 Insect creature tokens with flying and haste.
Repeat from step 3 for the remaining trigger.
Activate Ashnod's Altar four times by sacrificing the Insects, adding eight C.
Repeat.
This loop is a masterclass in turning raw mana into an unstoppable swarm. By equipping Tymora's Invoker with Illusionist's Bracers, its heavy activation cost yields four drawn cards instead of two, which in turn causes The Locust God to flood the board with four hasty Insect tokens. You then feed those freshly spawned tokens to Ashnod's Altar, generating the exact eight mana needed to fuel Tymora's Invoker all over again in a continuous, self-sustaining loop of draw, creation, and sacrifice.
