Enduring Renewal + Crystalline Crawler + Sunbond + Kokusho, the Evening Star + Carrion Feeder

Enduring Renewal

Crystalline Crawler

Sunbond

Kokusho, the Evening Star

Carrion Feeder

How it works

1. Cast Kokusho by paying 4.
2. Activate Carrion Feeder by sacrificing Kokusho.
3. When Kokusho dies, it and Enduring Renewal trigger.
4. Resolve the Enduring Renewal trigger, returning Kokusho from your graveyard to your hand.
5. Resolve the Kokusho trigger, causing each opponent to lose 5 life and you to gain life equal to the life lost this way.
6. Crystalline Crawler triggers, putting a number of +1/+1 counters on it equal to the life you gained.
7. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
8. Activate Crystalline Crawler's first ability six times by removing six +1/+1 counters from it, adding 4.
9. Repeat.

This cunning loop turns the legendary dragon Kokusho, the Evening Star into an endless engine of drain and rebirth, perfectly sustained by Enduring Renewal's passive ability to immediately bounce any creature that hits your graveyard back to your hand. To fund the casting costs, Carrion Feeder acts as the designated executioner, while Sunbond watches your lifegain soar and continuously pumps those life-swells into a massive pile of +1/+1 counters on Crystalline Crawler. You can then harvest Crystalline Crawler's counters for all the colored mana you need, feeding right back into re-casting Kokusho to drain your opponents out of the game entirely.
