Jegantha, the Wellspring + Horde of Notions + Yahenni, Undying Partisan + Garna, the Bloodflame

Jegantha, the Wellspring

Horde of Notions

Yahenni, Undying Partisan

Garna, the Bloodflame

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Yahenni 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 delightful loop transforms the five-color bounty of Jegantha, the Wellspring into an engine of endless rebirth, relying on Horde of Notions to repeatedly pull the Avatar right back out of the graveyard. By feeding Jegantha to Yahenni, Undying Partisan's sacrifice ability, you not only fuel the Horde's activation cost with colored mana, but you also ensure Yahenni grows into a lethal threat while gaining temporary indestructible safety. Meanwhile, Garna, the Bloodflame sits in the wings—though not explicitly tapped in the loop, Garna's flash and return trigger (or simply her presence granting haste, depending on how you assemble the wider board) help orchestrate this relentless cycle of sacrifice and resurrection.
