This ingenious loop relies on Horde of Notions and its ability to continually cheat the legendary Elemental Jegantha, the Wellspring right back out of the graveyard using the exact five-color mana it produces. To fuel this recursion, Jegantha is sacrificed to Bartolomé del Presidio, which conveniently grows larger with each iteration thanks to its built-in sacrifice outlet and counter-adding trigger. Meanwhile, Tannuk, Steadfast Second passively grants haste to your creatures—ensuring Jegantha can tap the very moment it hits the battlefield to restart the cycle without any summoning sickness slowing you down.
