Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Thousand-Year Elixir

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Thousand-Year Elixir

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 transforms the precise color requirements of Jegantha, the Wellspring into an endless engine of resurrection and mill. By tapping Jegantha for its restriction-heavy five-color mana and feeding it to Altar of Dementia, you fuel Horde of Notions, whose ability effortlessly pulls Jegantha right back out of the graveyard to repeat the cycle without ever needing to worry about generic mana restrictions. Meanwhile, Thousand-Year Elixir quietly supports the crew by granting haste-like activation privileges should you need to mix in its untapping utility, though the core loop relies entirely on Horde of Notions to recycle your sacrificed legend.
