This elegant mana-neutral loop relies on Biomancer's Familiar to reduce Emiel the Blessed's blink activation cost down to just one mana, which can be conveniently funded by tapping the very Treasure token that Galazeth Prismari generates upon re-entering the battlefield. Because Galazeth Prismari's static ability also turns your artifacts into mana sources for instants and sorceries, your entire board becomes primed to support your spells, though here it's entirely dedicated to constantly recycling Galazeth Prismari itself. Each iteration of this process triggers fresh enters-the-battlefield and leaves-the-battlefield events, giving you an endlessly repeating engine built entirely on cost reduction and repeatable blinking.
