Activate Slogurk by removing three +1/+1 counters from it, returning it from the battlefield to your hand.
When Slogurk leaves the battlefield, it triggers, returning three land cards from your graveyard to your hand.
Cast Slogurk by paying E due to Primal Prayers.
When Slogurk enters, Decoction Module triggers, causing you to get E.
Repeat.
This clever loop turns your graveyard into an endless engine by leveraging Slogurk, the Overslime’s unique ability to harvest its own counters and return land cards to your hand upon leaving the battlefield. You fuel Slogurk's counter-removal cost by repeatedly discarding lands to Dream Trawler, which conveniently triggers Slogurk to grow and sets up the land recovery you need. Meanwhile, Primal Prayers completely bypasses Slogurk's traditional mana cost by letting you recast it using energy, while Decoction Module seamlessly replaces that spent energy every single time Slogurk enters the battlefield anew.
