Basking Broodscale + Cleric Class + Soul's Attendant

Basking Broodscale

Cleric Class

Soul's Attendant

How it works

1. Gain life.
2. Cleric Class 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, Soul's Attendant triggers, causing you to gain 2 life.
5. Repeat from step 2.

This elegant loop transforms a single instance of life gain into a self-sustaining engine of growth and resources. It all begins when you gain life, which is amplified and turned into a +1/+1 counter on Basking Broodscale courtesy of Cleric Class. Placing that counter triggers the Broodscale itself to spawn an Eldrazi Spawn token, and the very act of that token entering the battlefield prompts Soul's Attendant to reward you with more life. That new lifegain loops right back into Cleric Class to restart the cycle, leaving you with an arbitrarily large creature, an endless army of tokens, and infinite colorless mana.
