Jegantha, the Wellspring + Horde of Notions + Phyrexian Altar + Urabrask the Hidden

Jegantha, the Wellspring

Horde of Notions

Phyrexian Altar

Urabrask the Hidden

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Phyrexian 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 intricate loop transforms Jegantha, the Wellspring into a self-sustaining engine by taking advantage of its unique color-restricted mana and Elemental creature type. By tapping Jegantha to produce the exact five-color mana requirement, you feed that energy directly into Horde of Notions' ability, which targets Jegantha in the graveyard and casts it for free. Phyrexian Altar acts as the necessary catalyst, letting you sacrifice Jegantha to fund subsequent loops while generating a spare color of mana to build up an infinite storm count and trigger count. Meanwhile, Urabrask the Hidden ensures that every time Jegantha returns to the battlefield, it immediately gains haste so the tap ability can be used again without delay.
