This loop is a masterclass in recycling, fueled entirely by the colorful activation of Jegantha, the Wellspring to pay the hefty five-color cost required by Horde of Notions. Once Jegantha is tapped for its mana, Bartolomé del Presidio acts as the sacrificial outlet to send the Elk Elemental right back to the graveyard. From there, Horde of Notions steps in to cast Jegantha straight out of the graveyard for free, all while Fires of Yavimaya passively grants your creatures haste so the newly re-summoned Jegantha can immediately tap and restart the cycle.
