Jegantha, the Wellspring + Horde of Notions + Thermopod + Akroma's Memorial

Jegantha, the Wellspring

Horde of Notions

Thermopod

Akroma's Memorial

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 ingenious loop transforms Jegantha, the Wellspring into a self-sustaining mana turbine by using its own colored mana restriction to feed the activation cost of Horde of Notions. You tap Jegantha for its five-color mana production, sacrifice it to Thermopod to generate the red mana needed alongside that five-color chunk, and then Horde of Notions uses that exact color spread to pull Jegantha right back out of the graveyard. Akroma's Memorial sits proudly on the battlefield to grant haste to Jegantha the moment it returns, allowing it to tap immediately and keep this infinite sacrifice and storm engine spinning forever.
