Yomiji, Who Bars the Way + Omarthis, Ghostfire Initiate + Ashnod's Altar

Yomiji, Who Bars the Way

Omarthis, Ghostfire Initiate

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Omarthis, adding CC.
2. When Omarthis dies, it and Yomiji trigger.
3. Resolve the Omarthis trigger, manifesting the top card of your library.
4. Resolve the Yomiji trigger, returning Omarthis from your graveyard to your hand.
5. Cast Omarthis by paying 2.
6. Repeat.

This elegant loop turns the legendary nature of Omarthis, Ghostfire Initiate into a self-sustaining engine fueled by Ashnod's Altar. Whenever you sacrifice the ghostly construct, the Altar rewards you with two colorless mana, which is just enough to recast Omarthis from your hand thanks to Yomiji, Who Bars the Way instantly bouncing it back from the graveyard whenever a legendary permanent hits the bin. As Omarthis continuously perishes and returns, its death trigger manifests your entire library card by card, flooding the battlefield with an overwhelming army.
