Jegantha, the Wellspring + Horde of Notions + Carrion Feeder + Purphoros, Bronze-Blooded

Jegantha, the Wellspring

Horde of Notions

Carrion Feeder

Purphoros, Bronze-Blooded

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Carrion Feeder 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 revolves around Jegantha, the Wellspring generating the exact five-color mana restriction ({W}{U}{B}{R}{G}) needed to fuel Horde of Notions' ability, which lets you repeatedly pull Jegantha straight back from the graveyard for free. To keep the engine running, Carrion Feeder acts as the designated sacrifice outlet to bin Jegantha each iteration, growing with +1/+1 counters while generating an endless chain of death triggers. Meanwhile, Purphoros, Bronze-Blooded sits quietly on the battlefield, utilizing its passive ability to grant your entire team haste so that Jegantha is immediately ready to tap for mana the moment it returns.
