This clever loop turns the mechanical engine of Earthcraft into a self-sustaining storm by using your basic Island to fuel Drowned Rusalka's discard-and-draw ability. Every time you cycle through your deck, The Locust God steps in to reward you by instantly spawning a flying 1/1 Insect token with haste. That newly minted token then feeds right back into Earthcraft, tapping itself to untap the land and keep the cycle going forever.
