Task Force + Animal Boneyard + Shaman en-Kor

Task Force

Animal Boneyard

Shaman en-Kor

How it works

1. Activate Shaman en-Kor by paying 0.
2. Task Force triggers, giving it +0/+3 until end of turn.
3. Repeat an arbitrarily large number of times.
4. Activate the land with Animal Boneyard attached by tapping it and sacrificing Task Force, causing you to gain life equal to Task Force's toughness.

This clever life-generating engine relies on Shaman en-Kor and its free, zero-mana targeting ability to rapidly inflate your toughness without ever passing priority. By repeatedly targeting Task Force with the Shaman's redirection effect, you trigger Task Force's growth ability over and over again, pushing its toughness to astronomical heights. Once your reserves are sufficiently massive, you simply cash in your creation with Animal Boneyard, sacrificing the pumped-up creature to its enchanted land ability to instantly net you an arbitrarily large amount of life.
