Mazirek, Kraul Death Priest + Evolution Witness + Tormod's Crypt

Mazirek, Kraul Death Priest

Evolution Witness

Tormod's Crypt

How it works

1. Cast Tormod's Crypt by paying 0.
2. Activate Tormod's Crypt by tapping and sacrificing it.
3. Mazirek triggers, putting a +1/+1 counter on Evolution Witness.
4. Evolution Witness triggers, returning Tormod's Crypt from your graveyard to your hand.
5. Resolve the Tormod's Crypt ability.
6. Repeat.

This elegant loop turns a humble zero-mana artifact into a relentless engine of growth and recursion. By sacrificing Tormod's Crypt, you trigger Mazirek, Kraul Death Priest to blanket your board in +1/+1 counters—which in turn wakes up Evolution Witness to fish the sacrificed Tormod's Crypt right back out of your graveyard. Because Tormod's Crypt costs nothing to cast, you can endlessly replay, crack, and recur it to pump out infinite storm count and arbitrarily large creatures.
