Slogurk, the Overslime + Primal Prayers + Skirge Familiar + Decoction Module

Slogurk, the Overslime

Primal Prayers

Skirge Familiar

Decoction Module

How it works

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

This clever loop transforms land cards into an endless fountain of black mana by leveraging Skirge Familiar to discard them into the graveyard, which immediately feeds Slogurk, the Overslime with +1/+1 counters. Once Slogurk accumulates three counters, you can bounce it back to your hand, triggering its leaves-the-battlefield ability to reclaim all three discarded lands and reset the engine. Primal Prayers then allows you to recast Slogurk using energy rather than mana, a cost offset entirely by Decoction Module generating fresh energy each time Slogurk enters the battlefield.
