Jegantha, the Wellspring + Horde of Notions + Bartolomé del Presidio + The Fire Crystal

Jegantha, the Wellspring

Horde of Notions

Bartolomé del Presidio

The Fire Crystal

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 brilliant loop leverages Jegantha, the Wellspring as both its own fuel and its own payload, starting when you tap it for the exact five-color mana required to pay Horde of Notions' ability. That activated ability immediately pulls Jegantha right back out of your graveyard to cast it for free, bypassing the restriction on Jegantha's mana since no generic costs are involved. Meanwhile, Bartolomé del Presidio acts as the reliable executioner in the graveyard engine, offering a sacrifice outlet that grows his own +1/+1 counters while letting you repeat the cycle endlessly. While The Fire Crystal isn't strictly necessary for the core loop to close, its presence on the battlefield grants your team haste and reduces red spell costs if you branch out into other synergies.
