Jegantha, the Wellspring + Horde of Notions + Bloodflow Connoisseur + Garna, the Bloodflame

Jegantha, the Wellspring

Horde of Notions

Bloodflow Connoisseur

Garna, the Bloodflame

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Bloodflow Connoisseur 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 relies on Jegantha, the Wellspring generating the exact five-color mana requirement for Horde of Notions, which then plucks Jegantha right back out of the graveyard for free. To keep the cycle spinning, Bloodflow Connoisseur acts as our sacrificial outlet, cleanly clearing Jegantha away each time so Horde of Notions can target it anew. We even have Garna, the Bloodflame standing by in the wings to tie it all together with haste and recursion if needed, though the core engine of Jegantha, Horde of Notions, and Bloodflow Connoisseur is all it takes to grind out endless triggers.
