This engine transforms your graveyard into a mana-and-cardhouse powerhouse by replacing scrys with pure draws. When you discard a card to pay for Skirge Familiar, you not only generate black mana, but you also trigger Curator of Mysteries to scry 1. Because Eligeth, Crossroads Augur completely replaces that scry with a card draw, you immediately replenish your hand to keep feeding the Familiar. It is a brilliant self-sustaining loop that turns your deck into your hand while flooding your mana pool.
