Slogurk, the Overslime

Primal Prayers

Guide of Souls

Ghostly Pilferer

How it works

1. Activate Ghostly Pilferer by discarding a land card.
2. Slogurk triggers, putting a +1/+1 counter on it.
3. Resolve the Ghostly Pilferer 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, Guide of Souls triggers, causing you to get E and gain 1 life.
9. Repeat.

This ingenious loop turns Ghostly Pilferer's discard outlet into a self-sustaining engine by pitching land cards directly into the graveyard, which in turn grows Slogurk, the Overslime with +1/+1 counters. Once Slogurk has gathered enough counters, you bounce it to your hand, triggering its leave-the-battlefield ability to immediately harvest those discarded lands right back to your hand. Primal Prayers then steps in to let you recast Slogurk for a mere {E} instead of its mana cost, while Guide of Souls rewards each of those repeated entries with a steady stream of life and energy to keep the cycle going infinitely.
