Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Akroma's Memorial

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Akroma's Memorial

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 relies on Jegantha, the Wellspring and its restricted color mana to fund Horde of Notions, which capitalizes on its ability to play targeted Elemental cards directly from the graveyard without paying their mana costs. Because Jegantha is an Elemental, Horde of Notions can continuously pull it back into play every time Altar of Dementia sacrifices it to mill cards based on its power. Akroma's Memorial sits safely on the battlefield passively granting your creatures haste, ensuring that Jegantha's tapping ability and all the resulting sacrifice and death triggers can repeat seamlessly into an infinite mill victory.
