Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Purphoros, Bronze-Blooded

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Purphoros, Bronze-Blooded

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 starts by tapping Jegantha, the Wellspring to harvest its color-restricted five-color mana. You then feed that exact mana directly into Horde of Notions' activated ability to pull Jegantha right back out of your graveyard and cast it without paying its mana cost. Altar of Dementia acts as the sacrifice engine that sends Jegantha back to the graveyard while turning each iteration into a chunk of mill, neatly fueling your engine without ever needing traditional generic mana. Meanwhile, Purphoros, Bronze-Blooded lurks quietly in the background, granting haste and ready to leverage all those repeating triggers whenever you need extra utility from your battlefield.
