Enduring Renewal + Crystalline Crawler + Sunbond + Pelakka Wurm + Blasting Station

Enduring Renewal

Crystalline Crawler

Sunbond

Pelakka Wurm

Blasting Station

How it works

1. Cast Pelakka Wurm by paying 4.
2. When Pelakka Wurm enters the battlefield, its first ability and Blasting Station trigger.
3. Resolve the Pelakka Wurm trigger, causing you to gain 7 life.
4. Crystalline Crawler triggers, putting seven +1/+1 counters on itself.
5. Resolve the Blasting Station trigger, untapping it.
6. Activate Crystalline Crawler's first ability seven times by removing seven +1/+1 counters from it, adding 4.
7. Activate Blasting Station by tapping it and sacrificing Pelakka Wurm.
8. When Pelakka Wurm dies, its second ability and Enduring Renewal trigger.
9. Resolve the Pelakka Wurm trigger, causing you to reveal the top card of your library and put it into your graveyard if its a creature card, or draw a card otherwise.
10. Resolve the Enduring Renewal trigger, returning Pelakka Wurm from your graveyard to your hand.
11. Resolve the Blasting Station ability, dealing 1 damage to any target.
12. Repeat.

This loop creates a self-sustaining engine by turning Pelakka Wurm's massive life-gain into a flurry of counters and damage. Every time the Wurm hits the battlefield, Blasting Station untaps and Sunbond would trigger, though the real magic happens as Crystalline Crawler absorbs the generated life-gain into a reservoir of mana counters. Sacrificing the Wurm to Blasting Station deals damage and triggers Enduring Renewal to instantly bounce the Wurm right back to your hand for another casting.
