Jegantha, the Wellspring + Horde of Notions + Umbral Collar Zealot + Dragonlord Kolaghan

Jegantha, the Wellspring

Horde of Notions

Umbral Collar Zealot

Dragonlord Kolaghan

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.

By utilizing Jegantha, the Wellspring and its restriction-free color-pie-spanning mana generation, you can fund Horde of Notions' activated ability entirely with colored mana, perfectly dodging Jegantha's inability to pay generic costs. Each iteration of this loop relies on Umbral Collar Zealot to seamlessly sacrifice Jegantha into the graveyard, where Horde of Notions can immediately pull it back onto the battlefield. While Dragonlord Kolaghan sits proudly in your deck or command zone as a terrifying emblem of this loop's payoff, the engine itself churns out endless death triggers, sacrifices, and surveils to bury your opponents under an avalanche of value.
