Peregrin Took + Cleric Class + Leonin Elder + Herd Baloth

Decks

How it works

You have a way to cause an artifact to enter the battlefield under your control.
Cleric Class is at least level two.

Cause an artifact to enter the battlefield under your control.
Leonin Elder triggers, causing you to gain 2 life due to Cleric Class.
Cleric Class triggers, putting a +1/+1 counter on Herd Baloth.
Herd Baloth triggers, creating a 4/4 Beast creature token and a Food artifact token.
When the Food enters the battlefield, Leonin Elder triggers, causing you to gain 2 life.
Repeat from step 3.
Once you have infinite Foods, you may sacrifice them to Peregrin Took's ability.
