Cleric Class + Herd Baloth + Haliya, Guided by Light

Cleric Class

Herd Baloth

Haliya, Guided by Light

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

This lively loop gets rolling the moment you trigger any initial lifegain, which Cleric Class amplifies while its Level 2 ability translates every lifegain event into a +1/+1 counter for Herd Baloth. In turn, those counters trigger Herd Baloth to continually spawn 4/4 green Beast tokens. Every single token that enters the battlefield causes Haliya, Guided by Light to trigger and feed you more life, which immediately loops back into Cleric Class to keep the counter train running endlessly.
