Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Dynaheir, Invoker Adept

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Dynaheir, Invoker Adept

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 looping mechanism is a brilliant showcase of color-filtering and graveyard recursion working in tandem. Jegantha, the Wellspring provides the exact five-color mana requirement for Horde of Notions, bypassing the typical resource restrictions since Jegantha's mana is specifically tailored to pay the five-color activation cost without needing generic mana. Once Jegantha is sacrificed to Altar of Dementia to mill your library and send the Elk Avatar back to the graveyard, Horde of Notions steps in to cast Jegantha straight from the graveyard for free. Meanwhile, Dynaheir, Invoker Adept sits on the board with her haste and ability-copying prowess, though the engine runs autonomously on the perfect synergy between Jegantha's mana production, Horde of Notions' resurrection, and Altar of Dementia's sacrificial mill.
