Jegantha, the Wellspring + Horde of Notions + Thermopod + The Fire Crystal

Jegantha, the Wellspring

Horde of Notions

Thermopod

The Fire Crystal

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 uses Horde of Notions as an engine to recur Jegantha, the Wellspring directly from the graveyard for free, its five-color activation perfectly funding the Elemental's steep ability cost. Thermopod steps in as the sacrifice outlet to convert Jegantha into the red mana needed to keep the cycle going while triggering endless deaths, while The Fire Crystal passively grants haste to ensure Jegantha is ready to tap the moment it returns to the battlefield.
