Familiars is a combo-control deck that wins by bouncing Sunscape Familiar with Snap and Ghostly Flicker loops to generate infinite mana and card draw through Mulldrifter and Sea Gate Oracle. Your primary plan is to burn them out before they assemble the loop, as your 20 direct damage spells put them on a very fast clock. Contaminated Ground is excellent here — slapping it on Azorius Chancery or another bounce land disrupts their mana engine and denies them the colored mana needed to loop, plus it replaces itself with a draw. Extract a Confession can strip a key piece like Ghostly Flicker or Archaeomancer from hand if you need to slow them down. Trim a couple Lightning Bolts and a Fiery Temper since God-Pharaoh's Faithful will gain them life and those slots are better used for disruption — your madness engine through Kitchen Imp and Sneaky Snacker still applies pressure efficiently.
