Archangel of Thune + Crystalline Crawler + Temple Elder + Pemmin's Aura

Archangel of Thune

Crystalline Crawler

Temple Elder

Pemmin's Aura

How it works

1. Activate Temple Elder by tapping it, causing you to gain life.
2. Archangel of Thune triggers, putting a +1/+1 counter on each creature you control.
3. Activate Crystalline Crawler ability by removing a +1/+1 counter from it, adding .
4. Activate Pemmin's Aura's ability by paying , untapping Temple Elder.
5. Repeat.

This charming loop is powered by Temple Elder, whose tap ability grants you a humble point of life during your turn. That tiny drop of life is all Archangel of Thune needs to trigger its glorious static ability, blanketing your board with +1/+1 counters—including a fresh counter onto Crystalline Crawler. You can then cash in that newly minted counter using Crystalline Crawler's mana ability to produce the blue mana required to fuel Pemmin's Aura, whose untap ability refreshes Temple Elder to start the cycle anew.
