Jegantha, the Wellspring + Horde of Notions + Carrion Feeder + Tannuk, Steadfast Second

Jegantha, the Wellspring

Horde of Notions

Carrion Feeder

Tannuk, Steadfast Second

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Carrion Feeder 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 ingenious loop turns Jegantha, the Wellspring into a self-recycling engine by using its own colored mana output to fuel Horde of Notions' ability, which pulls the Elk Avatar straight back out of the graveyard to handily bypass its restriction against generic mana costs. Carrion Feeder acts as the designated executioner, cleanly sacrificing Jegantha to trigger endless deaths while steadily growing with +1/+1 counters. Meanwhile, Tannuk, Steadfast Second stands by to grant haste to your creatures, ensuring that Jegantha is immediately ready to tap the moment it hits the battlefield again.
