Task Force + Animal Boneyard + Spirit en-Kor

Task Force

Animal Boneyard

Spirit en-Kor

How it works

1. Activate Spirit 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 sequence turns the zero-cost targeting ability of Spirit en-Kor into an engine for infinite stats. By repeatedly redirecting damage onto Task Force, you trigger its toughness-boosting ability over and over again without ever running out of resources. Finally, you cash in that monstrously inflated toughness by sacrificing Task Force to the land enchanted by Animal Boneyard, netting you an arbitrarily massive pile of life.
