Jegantha, the Wellspring + Horde of Notions + Fervor + Bloodflow Connoisseur

Jegantha, the Wellspring

Horde of Notions

Fervor

Bloodflow Connoisseur

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 fascinating loop turns Jegantha, the Wellspring into a self-contained mana engine, using its own color-restricted five-mana output to pay for Horde of Notions' ability to resurrect it directly from the graveyard. Because Horde of Notions requires all five distinct colors of mana—which Jegantha conveniently produces in full—the Elemental commander bridges the gap between each recursion effortlessly. Meanwhile, Fervor ensures that Jegantha gains haste the moment it returns to the battlefield so it can be tapped again immediately, while Bloodflow Connoisseur provides the vital sacrifice outlet to send Jegantha back to the graveyard along the way, even rewarding your persistence with infinite +1/+1 counters.
