Basking Broodscale + Leyline of Vitality + The Destined White Mage

Basking Broodscale

Leyline of Vitality

The Destined White Mage

How it works

1. Gain life.
2. The Destined White Mage triggers, putting a +1/+1 counter on Basking Broodscale.
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 ingenious loop turns a single instance of life gain into a self-sustaining engine of growth and resources. It all begins when you gain life, triggering The Destined White Mage to place a +1/+1 counter on Basking Broodscale. Because Basking Broodscale's adapt ability hasn't been used yet (or simply whenever counters are placed on it), its trigger creates a 0/1 Eldrazi Spawn token. That new token entering the battlefield immediately prompts Leyline of Vitality to grant you 1 life, looping right back into The Destined White Mage's trigger to repeat the entire cycle indefinitely.
