This potent loop harnesses Jegantha, the Wellspring to both generate the exact colored mana required and act as the recurrent sacrifice target, while Horde of Notions provides the engine to repeatedly pull it straight back from the graveyard for free. Meanwhile, Urabrask the Hidden ensures that Jegantha's return is immediate by granting it haste the moment it enters the battlefield. Finally, Goblin Bombardment converts this relentless cycle of life and death into an endless barrage of damage, letting you incinerate opponents and clean up the board entirely.
