Jegantha, the Wellspring + Horde of Notions + Thermopod + Gimli's Reckless Might

Jegantha, the Wellspring

Horde of Notions

Thermopod

Gimli's Reckless Might

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Thermopod 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 relies on a closed-circuit mana economy enabled by Thermopod and Jegantha, the Wellspring. You begin by tapping Jegantha to generate the exact five-color mana requirement for Horde of Notions, while Gimli's Reckless Might ensures your creatures have the right keywords on the board. You then feed Jegantha to Thermopod's sacrifice ability to add red mana, and use Horde of Notions' activated ability to pull Jegantha straight back out of your graveyard for free. Repeating this cycle yields an infinite storm count and endless sacrifice triggers, recycling the same legendary avatar over and over again.
