Jegantha, the Wellspring + Horde of Notions + Umbral Collar Zealot + Rising of the Day

Jegantha, the Wellspring

Horde of Notions

Umbral Collar Zealot

Rising of the Day

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 clever loop hinges on Jegantha, the Wellspring providing the exact five-color mana restriction-free color requirements needed to feed Horde of Notions' ability, which pulls Jegantha right back out of the graveyard after it hits the bin. To get Jegantha into the graveyard safely, you sacrifice it to Umbral Collar Zealot, which also filters your draws with its surveil ability along the way. Meanwhile, Rising of the Day ensures that every time Jegantha returns to the battlefield, its haste-granting static ability lets it tap immediately for mana without waiting around.
