Slogurk, the Overslime

Primal Prayers

Birgi, God of Storytelling // Harnfel, Horn of Bounty

Aetherstorm Roc

How it works

1. Activate Harnfel by discarding a land card.
2. Slogurk triggers, putting a +1/+1 counter on it.
3. Resolve the Harnfel 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, Aetherstorm Roc triggers, causing you to get E.
9. Repeat.

This clever loop turns the cycle of recycling lands into an engine for infinite resources by feeding Birgi, God of Storytelling // Harnfel, Horn of Bounty through its Harnfel, Horn of Bounty side to discard land cards, which continuously grows Slogurk, the Overslime and triggers its leaves-the-battlefield recovery ability. Once Slogurk bounces itself using those accumulated counters, Primal Prayers steps in to let you recast it for a mere energy counter, a cost heavily subsidized by the energy generated every time Aetherstorm Roc watches Slogurk re-enter the battlefield. Altogether, this creates an unstoppable loop that fuels your storm count and lets you dig through and cast your entire library.
