Jugan, the Rising Star + Nim Deathmantle + Crystalline Crawler + Carrion Feeder

Jugan, the Rising Star

Nim Deathmantle

Crystalline Crawler

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing Jugan.
2. Jugan dies, triggering itself and Nim Deathmantle.
3. Resolve the Jugan trigger, putting five +1/+1 counters on Crystalline Crawler.
4. Activate Crystalline Crawler's first ability three times by removing three +1/+1 counters from it, adding 3.
5. Resolve the Nim Deathmantle trigger from step 2, causing you to pay 4 to return Jugan from your graveyard to the battlefield, and attach Nim Deathmantle to it.
6. Resolve the Carrion Feeder ability from step 1, putting a +1/+1 counter on it.
7. Repeat.
