Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Samut, Voice of Dissent

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Samut, Voice of Dissent

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 loop turns Jegantha, the Wellspring into a self-sustaining engine by utilizing its unique color-intensive mana production to directly fund the activation cost of Horde of Notions. Because Jegantha's mana cannot be spent on generic costs, Horde of Notions provides the exact five-color fix needed to pull Jegantha straight back from the graveyard without paying its mana cost. Meanwhile, Altar of Dementia capitalizes on this continuous loop by turning Jegantha's recurring sacrifices into an overwhelming wave of milling power, while Samut, Voice of Dissent waits quietly in the wings to grant the hasty support needed for any other creatures involved.
