Jegantha, the Wellspring + Horde of Notions + Shilgengar, Sire of Famine + Thousand-Year Elixir

Jegantha, the Wellspring

Horde of Notions

Shilgengar, Sire of Famine

Thousand-Year Elixir

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Shilgengar 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 intricate loop begins by tapping Jegantha, the Wellspring to harvest the exact five-color mana required to fuel Horde of Notions, while Thousand-Year Elixir stands ready to bypass any summoning sickness concerns for Jegantha's tap ability. You then use Shilgengar, Sire of Famine to sacrifice Jegantha, turning that death into a Blood token and setting up the graveyard for Horde of Notions to immediately cast Jegantha right back onto the battlefield for free. Because Jegantha's mana restriction only forbids generic mana costs, the color-filtered mana it produces pays the exact color requirements needed to keep Horde of Notions' recursion engine spinning infinitely.
