Jegantha, the Wellspring

Horde of Notions

Umbral Collar Zealot

Mass Hysteria

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 mesmerizing loop turns Jegantha, the Wellspring into an endless cycle of rebirth, fueled entirely by its own tap ability and the colorful mana requirement of Horde of Notions. Because Jegantha's mana restriction specifically forbids generic mana, Horde of Notions steps in to bridge the gap, paying the exact five-color cost needed to cast Jegantha straight from the graveyard. The missing link for this engine is Umbral Collar Zealot, which neatly dispatches Jegantha to the graveyard while filtering your draws with surveil, and all of this happens at instant speed thanks to Mass Hysteria granting haste to ensure Jegantha can tap the very moment it returns.
