Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Dragonlord Kolaghan

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Dragonlord Kolaghan

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 transforms Jegantha, the Wellspring into a self-sustaining engine by relying on its unique color requirements to bypass traditional mana restrictions. You activate Jegantha's ability to generate the precise five-color mana needed to fuel Horde of Notions, which allows you to cast elementals directly from the graveyard. Right before that mana is spent, you feed Jegantha to Altar of Dementia to mill your opponent and send Jegantha back to the graveyard. Horde of Notions then brings Jegantha right back to the battlefield, ready to tap again and repeat the cycle. Dragonlord Kolaghan sits proudly in the command zone or 99 as a fellow elemental, ensuring your recurring setup benefits from its aggressive presence while keeping this multicolored loop completely airtight.
