Cleric Class + Herd Baloth + Case of the Uneaten Feast

Cleric Class

Herd Baloth

Case of the Uneaten Feast

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, Case of the Uneaten Feast triggers, causing you to gain 2 life.
5. Repeat from step 2.

This loop starts simply enough when you gain life, creating the initial spark that Cleric Class needs to place a +1/+1 counter on Herd Baloth thanks to its second level. That counter immediately rouses Herd Baloth to create a 4/4 green Beast token, which in turn triggers Case of the Uneaten Feast's entry ability to hand you back more life. Because Cleric Class's passive replacement effect quietly boosts any life gained by 1, that triggered life cushion is always enough to keep feeding the enchantment's lifegain needs and restart the whole cycle.
