Jegantha, the Wellspring + Horde of Notions + Umbral Collar Zealot + Tannuk, Steadfast Second

Jegantha, the Wellspring

Horde of Notions

Umbral Collar Zealot

Tannuk, Steadfast Second

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, generating infinite creature leaves-the-battlefield, entry, sacrifice, and death triggers alongside an infinite storm count and infinite surveil. Umbral Collar Zealot provides the necessary sacrifice outlet to bin Jegantha while feeding you card selection, and Tannuk, Steadfast Second ensures Jegantha and any other pieces can attack immediately upon returning. Finally, Horde of Notions steps in to cast Jegantha directly from the graveyard by precisely matching its five-color cost with the exact color-requirement restriction of Jegantha, the Wellspring's own generated mana.
