Cleric Class + Crystalline Crawler + Pemmin's Aura + Kwain, Itinerant Meddler

Cleric Class

Crystalline Crawler

Pemmin's Aura

Kwain, Itinerant Meddler

How it works

1. Activate Kwain by tapping it, causing you to draw a card and gain 2 life, and allowing each opponent to draw a card and gain 1 life.
2. Cleric Class triggers, putting a +1/+1 counter on Crystalline Crawler.
3. Activate Crystalline Crawler's first ability by removing a +1/+1 counter from it, adding .
4. Activate Pemmin's Aura's first ability by paying , untapping Kwain.
5. Repeat.

This clever loop turns the unassuming rabbit Kwain, Itinerant Meddler into a perpetual motion machine by pairing him with Pemmin's Aura to perpetually untap him for a single blue mana. To fuel that untap cost indefinitely, you leverage Crystalline Crawler's ability to trade its counters for mana, which are in turn constantly replenished because Cleric Class passively boosts your life gain and converts those triggers into fresh +1/+1 counters for the Crawler. As you cycle Kwain, Itinerant Meddler over and over, you draw through your entire deck while generating an avalanche of life and card draw for the table.
