This colorful loop uses Jegantha, the Wellspring as both its own fuel and its own recurrence target, tapping for a unique five-color mana restriction that conveniently matches the activation cost of Horde of Notions. To circumvent summoning sickness and keep the engine turning immediately upon resurrection, Thousand-Year Elixir lets Jegantha tap the moment it hits the battlefield, while Thermopod provides a reliable sacrifice outlet that turns each iteration into a productive red mana. As you cycle Jegantha endlessly from graveyard to battlefield and back, Horde of Notions casts it for free using the exact mana colors Jegantha provided, generating a torrential storm count and endless sacrifice triggers.
