This brilliant loop relies on Jegantha, the Wellspring to self-fund its own resurrection, since its activated ability conveniently yields the exact five-color mana requirement needed to pay for Horde of Notions' recursive ability. Because Jegantha must be sacrificed to fuel Blasting Station's damage output, Horde of Notions steps in to pull the legendary Elk back from the graveyard for free every single cycle. Meanwhile, Tyvar, Jubilant Brawler grants Jegantha the haste it needs to tap for mana the very moment it hits the battlefield, turning Blasting Station's creature-entry untap trigger into the final piece that makes this fiery loop self-sustaining.
