Slogurk, the Overslime + Primal Prayers + Decoction Module + Putrid Imp

Slogurk, the Overslime

Primal Prayers

Decoction Module

Putrid Imp

How it works

1. Activate Putrid Imp by discarding a land card.
2. Slogurk triggers, putting a +1/+1 counter on it.
3. Resolve the Putrid Imp ability.
4. Repeat from step 1 two additional times.
5. Activate Slogurk by removing three +1/+1 counters from it, returning it from the battlefield to your hand.
6. When Slogurk leaves the battlefield, it triggers, returning three land cards from your graveyard to your hand.
7. Cast Slogurk by paying E due to Primal Prayers.
8. When Slogurk enters, Decoction Module triggers, causing you to get E.
9. Repeat.

This ingenious loop turns a graveyard into a self-sustaining engine by letting you repeatedly dump and retrieve lands using Putrid Imp's free discard ability, which pumps Slogurk, the Overslime with counters. Once Slogurk bounces itself by removing those counters, its leave-the-battlefield trigger pulls those discarded lands right back to your hand, fueling your resources. Meanwhile, Primal Prayers allows you to recast Slogurk using energy instead of mana, and Decoction Module kicks in upon that entry to replenish your energy reserves while keeping the cycle going.
