Task Force + Animal Boneyard + Nomads en-Kor

Task Force

Animal Boneyard

Nomads en-Kor

How it works

1. Activate Nomads 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 loop turns the zero-cost targeting ability of Nomads en-Kor into a massive toughness pump for Task Force, since every single redirection counts as targeting it with an ability. Because Nomads en-Kor's ability costs nothing to activate, you can repeat this targeting process an arbitrary number of times to grow Task Force's toughness into the thousands. Finally, you cash in that monstrous stat line by sacrificing Task Force to Animal Boneyard, capitalizing on the enchanted land's activated sacrifice ability to gain an arbitrarily large amount of life.
