Jegantha, the Wellspring + Horde of Notions + Umbral Collar Zealot + Hammer of Purphoros

Jegantha, the Wellspring

Horde of Notions

Umbral Collar Zealot

Hammer of Purphoros

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 turns Jegantha, the Wellspring into a self-recycling engine, fueled entirely by its own tap ability. Because Jegantha taps for the exact five-color mana requirement demanded by Horde of Notions, you can repeatedly cast the legendary Elk from your graveyard for free. To feed the cycle, Umbral Collar Zealot acts as the sacrificial outlet that bins Jegantha each iteration while smoothing your draws with its surveil trigger, and Hammer of Purphoros grants your commander immediate haste so it can tap the very moment it returns.
