This intricate loop uses Emry, Lurker of the Loch to repeatedly pull Lion's Eye Diamond from your graveyard, sacrificing the Diamond for mana right after it resolves. Each time you cast the Lion's Eye Diamond, Displacer Kitten triggers its Avoidance ability to blink Emry, Lurker of the Loch, resetting her tap ability and triggering a fresh mill of four cards upon her return. Meanwhile, The Fire Crystal passively grants your creatures haste so Emry can tap immediately, while also offering cost reduction and token copying capabilities if you need to branch out your strategy. Together, these pieces turn a simple artifact-casting loop into an endless cycle of self-mill, mana production, and trigger generation.
