This mesmerizing loop relies on Jegantha, the Wellspring generating the exact five-color mana required to fuel Horde of Notions, which can immediately cast Jegantha right back out of the graveyard after it falls. Woe Strider acts as the necessary executioner, cleanly sacrificing Jegantha to trigger its demise while simultaneously letting you sculpt your draws with its scry ability. Meanwhile, Thousand-Year Elixir quietly provides the vital logistical support—though not explicitly tapped in the execution steps, its static ability grants Jegantha the haste-like privilege to tap for mana the very moment it returns, completing a seamless and self-sustaining engine.
