Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Tyvar, Jubilant Brawler

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Tyvar, Jubilant Brawler

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 recursive loop relies on Jegantha, the Wellspring to generate the exact five-color mana required to fuel Horde of Notions, which can cast Jegantha straight out of your graveyard whenever it hits the bin. Tyvar, Jubilant Brawler makes this engine possible by granting Jegantha the haste it needs to tap for mana immediately upon returning to the battlefield. Finally, Altar of Dementia acts as the catalyst that sends Jegantha back to the graveyard to be replayed, milling your opponents out in the process.
