Jegantha, the Wellspring + Horde of Notions + Maelstrom Wanderer + Bartolomé del Presidio

Jegantha, the Wellspring

Horde of Notions

Maelstrom Wanderer

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 loop relies on Jegantha, the Wellspring generating the exact five-color mana requirement—{W}{U}{B}{R}{G}—needed to fuel Horde of Notions' ability, which lets you recast Jegantha directly from the graveyard without paying its mana cost. Because Jegantha can't be tapped for generic mana, Horde of Notions' strict color requirements are uniquely satisfied. To keep the cycle going, Bartolomé del Presidio acts as the sacrifice outlet, sending Jegantha to the graveyard so it can be targeted again, all while growing larger with each iteration. Meanwhile, Maelstrom Wanderer sits comfortably on the battlefield, granting the necessary haste to ensure that your repeatedly reborn Jegantha can tap for mana the moment it re-enters play.
