Jegantha, the Wellspring + Horde of Notions + Fervor + Bartolomé del Presidio

Jegantha, the Wellspring

Horde of Notions

Fervor

Bartolomé del Presidio

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Bartolomé del Presidio 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 lovely loop turns Jegantha, the Wellspring into an endless engine of rebirth, fueled entirely by its own five-color mana production. Each iteration requires a hefty infusion of colors, but Jegantha's tap ability conveniently provides the exact five-mana requirement needed for Horde of Notions to fish that very same Elk Elemental out of the graveyard for free. To keep the cycle going, Bartolomé del Presidio acts as the willing executioner, instantly sacrificing Jegantha to trigger another death while growing larger with each repetition. Meanwhile, Fervor quietly ensures that Jegantha gains haste upon its return, allowing it to tap immediately for mana without waiting around and letting the entire sequence repeat indefinitely.
