This looping sequence turns Jegantha, the Wellspring into an endless source of ammunition, powered by its own unique ability to tap for the exact five-color mana requirement needed to activate Horde of Notions. By using Horde of Notions to repeatedly pull Jegantha straight from the graveyard back onto the battlefield without paying its mana cost, you create a seamless resurrection loop. Goblin Bombardment provides the necessary sacrifice outlet to bin Jegantha and simultaneously translate each iteration into direct damage, while Purphoros, Bronze-Blooded sits quietly on the battlefield ensuring that every returned incarnation of Jegantha instantly gains haste right out of the graveyard to keep the loop functioning.
