Jegantha, the Wellspring + Horde of Notions + Umbral Collar Zealot + Urabrask the Hidden

Jegantha, the Wellspring

Horde of Notions

Umbral Collar Zealot

Urabrask the Hidden

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Umbral Collar Zealot 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 loop hinges on a clever workaround to Jegantha, the Wellspring's color restriction, which its innate colored mana solves perfectly by feeding the exact five-color requirement for Horde of Notions's activated ability. By paying that exact mana to cast Jegantha directly from your graveyard, you bypass needing generic mana entirely while setting up a continuous cycle. Umbral Collar Zealot provides the crucial sacrifice outlet to put Jegantha back into the graveyard, while also smoothing your draws with surveil along the way. Finally, Urabrask the Hidden ensures that Jegantha's re-entries are immediate threats by granting it haste as soon as it hits the battlefield.
