Rakdos Sacrifice relies on Witch's Oven and Deadly Dispute recursion, and Get Lost gives them Map tokens which can fuel Sentinel-style value, so trimming a couple copies is fine while sweepers stay in against Cauldron Familiar and Eyetwitch. Three Steps Ahead can counter Fable of the Mirror-Breaker or Mayhem Devil, or draw cards to keep pace with their card advantage engine. Extra Beza, the Bounding Spring copies provide life gain against their damage-based Mayhem Devil plan and go over the top in a longer game. Keep Temporary Lockdown and Supreme Verdict as your primary answers to their wide, cheap board.
