Jegantha, the Wellspring + Horde of Notions + Umbral Collar Zealot + Thousand-Year Elixir

Jegantha, the Wellspring

Horde of Notions

Umbral Collar Zealot

Thousand-Year Elixir

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 transforms Jegantha, the Wellspring into a self-sustaining engine by repeatedly sending the Elk Avatar to the graveyard and back. Because Jegantha's tap ability produces the exact five-color mana requirement for Horde of Notions, you can instantly recast it from the graveyard each time Umbral Collar Zealot sends it there for a sacrifice. Meanwhile, Thousand-Year Elixir quietly pulls double duty, ensuring Jegantha can tap the very moment it enters the battlefield without waiting for summoning sickness to wear off.
