Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Kratos, God of War

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Kratos, God of War

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 intricate loop turns Jegantha, the Wellspring into an endless recursion engine, fueled directly by its own restrictive mana production to pay the activation cost of Horde of Notions. Because Horde of Notions lets you play that Elemental straight from the graveyard without paying its mana cost, you can repeatedly feed Jegantha to Altar of Dementia to mill your opponents out while generating infinite enters-the-battlefield, death, and sacrifice triggers. Meanwhile, Kratos, God of War grants haste so that Jegantha is immediately ready to tap again the moment it returns to the battlefield, effortlessly binding this colorful crew into an infinite loop.
