Slogurk, the Overslime + Primal Prayers + Ayula's Influence + Aetherstorm Roc

Slogurk, the Overslime

Primal Prayers

Ayula's Influence

Aetherstorm Roc

How it works

1. Activate Ayula's Influence by discarding a land card.
2. Slogurk triggers, putting a +1/+1 counter on it.
3. Resolve the Ayula's Influence ability, creating a 2/2 Bear creature token.
4. When the Bear enters, Aetherstorm Roc triggers, causing you to get E.
5. Repeat from step 1 two additional times.
6. Activate Slogurk by removing three +1/+1 counters from it, returning it from the battlefield to your hand.
7. When Slogurk leaves the battlefield, it triggers, returning three land cards from your graveyard to your hand.
8. Cast Slogurk by paying E due to Primal Prayers.
9. When Slogurk enters, Aetherstorm Roc triggers, causing you to get E.
10. Repeat.

This clever loop transforms discarded lands into a perpetual engine by letting Ayula's Influence fuel a steady stream of Bear tokens. Each of those creature entries triggers Aetherstorm Roc to continually stockpile energy counters, which in turn bypasses traditional mana costs to recast Slogurk, the Overslime via Primal Prayers. As Slogurk cycles on and off the battlefield, its leaves-the-battlefield trigger recycles your discarded land cards right back to your hand, sustaining the entire sequence indefinitely.
