Promised Kannushi + Ashes of the Fallen + Ashnod's Altar + Energy Refractor

Promised Kannushi

Ashes of the Fallen

Ashnod's Altar

Energy Refractor

How it works

1. Activate Ashnod's Altar by sacrificing Promised Kannushi, adding CC.
2. When Promised Kannushi dies, its soulshift ability triggers, returning itself from your graveyard to your hand.
3. Activate Energy Refractor by paying 2, adding .
4. Cast Promised Kannushi by paying .
5. Repeat.

This clever loop turns Ashnod's Altar into a self-contained engine by using Ashes of the Fallen to rewrite the rules of your graveyard, ensuring Promised Kannushi always counts as a Spirit no matter where it rests. When you sacrifice Promised Kannushi to the Altar for two colorless mana, its Soulshift 7 trigger effortlessly plucks itself right back out of the graveyard. Energy Refractor steps in to convert that raw colorless energy into the precise green mana required to recast Promised Kannushi, closing the loop to generate an endless stream of artifact-fueled sacrifices, creature entries, and storm count.
