Jegantha, the Wellspring + Horde of Notions + Phyrexian Altar + Mass Hysteria

Jegantha, the Wellspring

Horde of Notions

Phyrexian Altar

Mass Hysteria

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Phyrexian Altar 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 elegant loop turns Jegantha, the Wellspring into an endless engine of rebirth, utilizing its own restrictive ability to feed the very cost that brings it back. By tapping Jegantha for its distinct five-color mana, you can immediately sacrifice it to Phyrexian Altar to generate the colored mana required to activate Horde of Notions. Horde of Notions then pulls Jegantha straight from the graveyard back onto the battlefield for free, restarting the cycle while Mass Hysteria ensures that summoning sickness never slows down your newly returned Elemental.
