This clever loop turns Jegantha, the Wellspring into a self-sustaining mana and sacrifice engine. By using Jegantha's unique ability to generate all five colors of mana—which neatly matches the exact color requirements needed for Horde of Notions—you can repeatedly pull Jegantha straight out of your graveyard. Thermopod acts as the sacrificial outlet that turns each iteration into a red mana while sending Jegantha back to the graveyard to be recast. Meanwhile, Tyvar, Jubilant Brawler pulls double duty: his static ability grants Jegantha the haste it needs to tap the very moment it returns to the battlefield, while his +1 ability can even help untap your engine pieces if needed.
