Enduring Renewal + Crystalline Crawler + Light of Promise + Pelakka Wurm + Ashnod's Altar

Enduring Renewal

Crystalline Crawler

Light of Promise

Pelakka Wurm

Ashnod's Altar

How it works

1. Cast Pelakka Wurm by paying 4.
2. When Pelakka Wurm enters the battlefield, its first ability triggers, causing you to gain 7 life.
3. Crystalline Crawler triggers, putting seven +1/+1 counters on itself.
4. Activate Crystalline Crawler's first ability five times by removing five +1/+1 counters from it, adding 2.
5. Activate Ashnod's Altar by sacrificing Pelakka Wurm, adding CC.
6. When Pelakka Wurm dies, its second ability and Enduring Renewal trigger.
7. 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.
8. Resolve the Enduring Renewal trigger, returning Pelakka Wurm from your graveyard to your hand.
9. Repeat.

This loop transforms the massive lifecycle of Pelakka Wurm into an engine of absolute abundance, heavily anchored by Ashnod's Altar providing the sacrificial outlet to feed the cycle. Every time the Wurm enters and leaves the battlefield, Enduring Renewal swoops in to instantly rescue it from the graveyard straight back to your hand, allowing you to replay it endlessly. Meanwhile, Crystalline Crawler acts as a magnificent mana-and-counter battery; fueled by the influx of +1/+1 counters triggered from Light of Promise whenever the Wurm's entrance grants you life, the Crawler effortlessly converts those counters into the exact colors needed to cast the Wurm again while leaving a surplus of colorless energy behind.
