Cleric Class + Trostani, Selesnya's Voice + Herd Baloth

Cleric Class

Trostani, Selesnya's Voice

Herd Baloth

How it works

1. Gain life.
2. Cleric Class triggers, putting a +1/+1 counter on Herd Baloth.
3. Herd Baloth triggers, creating a creature token.
4. When the creature token enters the battlefield, Trostani triggers, causing you to gain 5 life.
5. Repeat from step 2.

This elegant loop feeds entirely on itself once you initiate the very first life gain, turning a tiny spark into a massive, unstoppable cascade. Trostani, Selesnya's Voice acts as the engine's heart, converting the birth of every new Beast token into a burst of life that fuels the rest of the machinery. That incoming life is boosted by Cleric Class, whose replacement effect ensures you always trigger its second-level ability to place a +1/+1 counter on Herd Baloth. In turn, Herd Baloth's triggered ability rewards that counter by spawning a brand new 4/4 token, which brings Trostani right back around to restart the entire sequence.
