Jegantha, the Wellspring

Horde of Notions

Ashnod's Altar

Dynaheir, Invoker Adept

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Ashnod's 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 fascinating engine transforms Jegantha, the Wellspring into a self-sustaining loop by using Ashnod's Altar to sacrifice the Elk Avatar and generate colorless mana. Horde of Notions then steps in, utilizing its ability to repeatedly pull Jegantha straight back out of your graveyard for free. Meanwhile, Dynaheir, Invoker Adept ensures your creatures keep pace by granting haste and copying abilities when heavy mana costs are met, allowing you to easily churn out infinite sacrifices and death triggers.
