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

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Urabrask the Hidden

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Altar of Dementia 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 recursion loop harnesses Jegantha, the Wellspring as both its own mana source and its own recurring threat, tapping for the exact five-color mana requirement needed to bring it back. Horde of Notions provides the engine to continuously pull Jegantha straight from the graveyard for free without paying its mana cost, while Altar of Dementia instantly bins the Elk Elemental every cycle to fuel the loop. Meanwhile, Urabrask the Hidden ensures that Jegantha's return is met with immediate haste, allowing the creature to tap for mana all over again the very moment it hits the battlefield.
