Soul's Attendant + Heliod, Sun-Crowned + Herd Baloth

Soul's Attendant

Heliod, Sun-Crowned

Herd Baloth

How it works

1. Gain any amount of life.
2. Heliod triggers, putting a +1/+1 counter on Herd Baloth.
3. Herd Baloth triggers, creating a 4/4 Beast creature token.
4. When the Beast enters the battlefield, Soul's Attendant triggers, causing you to gain 1 life.
5. Repeat.

This loop is a masterclass in recursive growth, turning a single instance of life gain into an unending cascade of creature generation. The engine starts when you gain life, which fires off Heliod, Sun-Crowned and its ability to place a +1/+1 counter onto Herd Baloth. That counter placement immediately triggers Herd Baloth to birth a 4/4 green Beast token, and as that new Beast enters the battlefield, Soul's Attendant spots the creature and rewards your patience by feeding you 1 life. That newly gained life point loops straight back into Heliod, Sun-Crowned to start the cycle anew, letting you flood the board with infinite beasts, triggers, and life while rapidly growing your Herd Baloth into a towering titan.
