Jegantha, the Wellspring + Horde of Notions + Phyrexian Altar + Tyvar, Jubilant Brawler

Jegantha, the Wellspring

Horde of Notions

Phyrexian Altar

Tyvar, Jubilant Brawler

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 clever engine transforms Jegantha, the Wellspring into a self-sustaining loop by leveraging its unique typing as an Elemental. Because Tyvar, Jubilant Brawler grants your creatures the ability to be tapped for mana the turn they arrive—or immediately after returning—Jegantha can be sacrificed to Phyrexian Altar to generate the colored mana needed for Horde of Notions. That five-color activation fee allows Horde of Notions to pull Jegantha straight back out of the graveyard without paying its mana cost, creating an infinite cycle of sacrifices and returns.
