Jegantha, the Wellspring + Horde of Notions + Thermopod + Anger

Jegantha, the Wellspring

Horde of Notions

Thermopod

Anger

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Thermopod 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 clever loop harnesses Jegantha, the Wellspring as both its own fuel and its own recursion target, tapping it to generate the exact five-color mana requirement needed for Horde of Notions' activated ability. By feeding Jegantha to Thermopod right after tapping it, you turn that color-restricted mana into red mana while sending the Elk to the graveyard, ready for Horde of Notions to pull it right back onto the battlefield for free. Meanwhile, Anger rests in your graveyard to ensure that whenever Jegantha returns, it immediately possesses the haste required to tap for mana all over again.
