Jegantha, the Wellspring + Horde of Notions + Shilgengar, Sire of Famine + Tuktuk Rubblefort

Jegantha, the Wellspring

Horde of Notions

Shilgengar, Sire of Famine

Tuktuk Rubblefort

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Shilgengar 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 restriction required to activate Horde of Notions, which then plucks Jegantha right back out of the graveyard. Shilgengar, Sire of Famine acts as the engine's heart, turning Jegantha's repetitive sacrifice into a steady stream of Blood tokens. Finally, Tuktuk Rubblefort ensures that whenever Jegantha returns, it isn't burdened by summoning sickness and can tap immediately for the next iteration.
