Jegantha, the Wellspring + Horde of Notions + Ashnod's Altar + Kratos, God of War

Jegantha, the Wellspring

Horde of Notions

Ashnod's Altar

Kratos, God of War

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Ashnod's Altar by sacrificing Jegantha.
3. Activate Horde of Notions by paying , causing you to cast Jegantha from your graveyard without paying its mana cost.
4. Repeat.

This clever loop relies on Jegantha, the Wellspring to generate the exact five-color mana required to fuel Horde of Notions, which can pull Jegantha right back out of the graveyard for free. To keep the engine running, Ashnod's Altar steps in to sacrifice Jegantha each iteration, generating a steady stream of colorless mana while setting up the graveyard recursion. Meanwhile, Kratos, God of War quietly ensures that haste is globally granted to keep any timing restrictions at bay, allowing the loop to execute instantly without summoning sickness getting in the way.
