Jegantha, the Wellspring + Horde of Notions + Viscera Seer + Dynaheir, Invoker Adept

Jegantha, the Wellspring

Horde of Notions

Viscera Seer

Dynaheir, Invoker Adept

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Viscera Seer 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 harnesses Jegantha, the Wellspring as both its own mana source and its own recurring threat, since its distinct mana cost satisfies its companion restriction while perfectly feeding Horde of Notions' ability. By paying the exact five-color mana required, Horde of Notions pulls Jegantha straight out of the graveyard to hand-deliver another five-color payload without ever needing generic mana. Meanwhile, Viscera Seer acts as the necessary outlet to bin Jegantha for free while letting you sift through your library with infinite scry triggers. While Dynaheir, Invoker Adept is part of the package, the core engine effortlessly spins out endless sacrifices, enters-the-battlefield effects, and storm count on demand.
