Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Maelstrom Wanderer

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Maelstrom Wanderer

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 clever loop uses Horde of Notions as the engine, paying its colorful five-mana activation cost using the exact color requirements provided by Jegantha, the Wellspring. Once Jegantha is brought back from the graveyard directly onto the battlefield, Altar of Dementia turns that recurrence into fuel by sacrificing the creature to mill away your library. Meanwhile, Maelstrom Wanderer passively grants haste to your creatures so Jegantha is ready to tap for mana immediately upon returning, completing a seamless cycle that mills out your opponents entirely.
