Basking Broodscale + Sunbond + Thunder of Unity

Basking Broodscale

Sunbond

Thunder of Unity

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, Thunder of Unity triggers, causing you to gain 1 life and each opponent to lose 1 life.
5. Repeat from step 2.

This loop transforms a single instance of life gain into an unstoppable cascade of growth and drain, starting when Thunder of Unity's second chapter gives your creatures a life-draining entry trigger. Once Sunbond enchants Basking Broodscale, any life you gain funnels straight back into the Broodscale as a +1/+1 counter. That counter placement sparks Basking Broodscale's own ability to birth an Eldrazi Spawn token, which immediately triggers Thunder of Unity's life gain and restarts the whole cycle.
