Basking Broodscale + Cleric Class + Social Climber

Basking Broodscale

Cleric Class

Social Climber

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, Social Climber triggers, causing you to gain 2 life.
5. Repeat from step 2.

This looping engine starts spinning the moment you gain a single point of life, which immediately triggers Cleric Class to place a +1/+1 counter on Basking Broodscale. That counter placement coaxes Basking Broodscale into spawning an Eldrazi Spawn token, whose entrance into the battlefield rouses Social Climber's alliance ability to net you more life. Because Cleric Class's passive lifegain bonus ensures you always net positive life from Social Climber, the entire cycle feeds back into itself indefinitely, churning out boundless counters, tokens, and colorless mana.
