Basking Broodscale + Leyline of Vitality + Sunbond

Basking Broodscale

Leyline of Vitality

Sunbond

How it works

1. Gain life.
2. Basking Broodscale triggers, putting a +1/+1 counter on itself.
3. Basking Broodscale triggers, creating a creature token.
4. When the creature token enters the battlefield, Leyline of Vitality triggers, causing you to gain 1 life.
5. Repeat from step 2.

This clever loop turns a single instance of lifegain into a self-sustaining engine of growth. It all starts when Leyline of Vitality triggers off a creature entering, granting you life that Sunbond immediately translates into a +1/+1 counter for Basking Broodscale. Basking Broodscale's own triggered ability responds to that counter by spawning an Eldrazi Spawn, which gracefully loops right back into Leyline of Vitality's entry trigger to keep the cycle spinning forever.
