This brilliant loop relies on Displacer Kitten’s ability to constantly reset Invasion of Arcavios whenever you cast a noncreature spell, turning each blink into a tutor to keep your hand perpetually stocked with answers. You start by firing off Dark Ritual to generate the initial black mana, triggering the Kitten to exile and return your Siege so you can fetch your next piece. From there, you use Invasion of Arcavios's back face, Invocation of the Founders, to duplicate your spells while chaining Dark Ritual back and forth to net infinite mana, storm, and casts of your chosen instant or sorcery.
