Jegantha, the Wellspring + Horde of Notions + Temur Ascendancy + Bartolomé del Presidio

Jegantha, the Wellspring

Horde of Notions

Temur Ascendancy

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. When Jegantha enters, Temur Ascendancy triggers, allowing you to draw a card.
5. Repeat.

This clever engine turns Jegantha, the Wellspring into a self-sustaining sacrifice loop by using Horde of Notions to repeatedly pull the elk avatar straight from the graveyard. Because Jegantha's tapped ability provides the exact five-color mana requirement needed to activate Horde of Notions, the loop pays for itself entirely while Bartolomé del Presidio safely dispatches Jegantha each iteration to feed the graveyard. Meanwhile, Temur Ascendancy acts as the engine's primary payoff, translating every recurring entry into an endless stream of card draw while granting all your creatures haste.
