Jegantha, the Wellspring + Horde of Notions + Ashnod's Altar + Rising of the Day

Jegantha, the Wellspring

Horde of Notions

Ashnod's Altar

Rising of the Day

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Ashnod's Altar 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 turns Jegantha, the Wellspring into a self-sustaining engine by tapping it for the exact five-color mana requirement needed to activate Horde of Notions. Because Horde of Notions lets you cast that exact same Elemental straight from the graveyard for free, you can feed Jegantha to Ashnod's Altar in between cycles to harvest a steady stream of colorless mana while setting up the next recursion. Meanwhile, Rising of the Day quietly ensures that Jegantha's re-entries happen smoothly with immediate haste, letting you repeat this explosive loop endlessly to drown the table in infinite sacrifice triggers and colorless mana.
