Daru Spiritualist + Animal Boneyard + Warrior en-Kor

Daru Spiritualist

Animal Boneyard

Warrior en-Kor

How it works

1. Activate Warrior en-Kor by paying 0, targeting Daru Spiritualist.
2. Daru Spiritualist triggers, giving it +0/+2 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 Daru Spiritualist, causing you to gain life equal to Daru Spiritualist's toughness.

This clever loop relies on the zero-cost targeting ability of Warrior en-Kor to repeatedly poke Daru Spiritualist, whose passive creature type makes it a valid recipient while triggering its ability to pump its toughness to astronomical heights. Because Warrior en-Kor's redirection costs nothing, you can repeat this process as many times as you like without spending any mana. Finally, you cash in that accumulated toughness by sacrificing the boosted Cleric to the land enchanted by Animal Boneyard, turning an arbitrarily large stat boost into a massive, game-winning burst of life.
