Familiars is a combo-control deck that generates infinite mana and card draw through Ghostly Flicker and Ephemerate loops with Archaeomancer and Sunscape Familiar, eventually winning with a large Mulldrifter or God-Pharaoh's Faithful life drain. Your primary game plan of ramping into large threats is mostly intact — you just need to survive the combo turn. Weather the Storm is your best sideboard card here, gaining massive life off your own spells to survive their drain loops. Cast into the Fire answers God-Pharaoh's Faithful, their primary win condition, and can also exile key artifacts if needed. Cut the high-cost, low-impact threats like Bannerhide Krushok and Sagu Wildling that are too slow to matter if they assemble their loop.
