Familiars is a combo-control deck that wins by looping Snap and Ghostly Flicker with Sunscape Familiar to generate free mana, then uses Archaeomancer to recur those spells indefinitely while gaining infinite life via God-Pharaoh's Faithful. Duress comes in as a sorcery to strip key combo enablers like Ghostly Flicker, Meeting of Minds, or their counterspells before they can set up. Snuff Out provides free instant-speed removal to answer Archaeomancer at any point, including mid-combo, which is critical for breaking the loop. Faerie Macabre exiles instants and sorceries directly from their graveyard as a free activated ability, preventing Archaeomancer from recursing Snap or Ghostly Flicker and disrupting the engine at its core. Pestilence is a powerful threat they struggle to answer outside of Dust to Dust in their sideboard, so protect it and use it to keep their small creatures like Sunscape Familiar and Sea Gate Oracle off the board.
