Daru Spiritualist + Shaman en-Kor + Miren, the Moaning Well

Daru Spiritualist

Shaman en-Kor

Miren, the Moaning Well

How it works

1. Activate Shaman en-Kor's first ability by paying 0, targeting Daru Spiritualist.
2. Daru Spiritualist triggers, causing itself to get +0/+2 until end of turn.
3. Resolve the Shaman en-Kor ability, causing the next one damage dealt to Shaman en-Kor this turn to be dealt to Daru Spiritualist instead.
4. Repeat an arbitrarily large number of times.
5. Activate Miren's second ability by paying 3, tapping it and sacrificing Daru Spiritualist, causing you to gain life equal to Daru Spiritualist's toughness.

This charming little engine relies on Shaman en-Kor's free, zero-mana targeting ability to repeatedly point at Daru Spiritualist, which safely pumps its toughness through the roof without expending any resources. Because Shaman en-Kor's redirection ability doesn't actually require the target to take damage to trigger the cleric's defense mechanism, you can loop this interaction an arbitrarily large number of times. Once your cleric's toughness is practically infinite, you cash it all in with Miren, the Moaning Well to sacrifice Daru Spiritualist and net yourself an immense, game-winning mountain of life.
