Jegantha, the Wellspring + Horde of Notions + Thermopod + Garna, the Bloodflame

Jegantha, the Wellspring

Horde of Notions

Thermopod

Garna, the Bloodflame

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 fiery loop turns Jegantha, the Wellspring into an endless engine of five-color mana and sacrificial fuel. By tapping Jegantha for its restriction-laden rainbow mana, you can immediately sacrifice it to Thermopod to generate a red mana and send the Elk Avatar back to your graveyard. From there, Horde of Notions steps in with its activated ability, using that exact colored mana profile to pull Jegantha straight back to the battlefield for free. Garna, the Bloodflame sits as a steadfast pillar over the graveyard, though the loop bypasses needing Garna's return trigger by recasting Jegantha directly through the Horde's elemental magic instead.
