Rakdos Reanimator is one of the fastest decks in Legacy and will frequently attempt a turn-one kill via Reanimate or Shallow Grave on a discarded Griselbrand or Archon of Cruelty. Grafdigger's Cage is the most important card in your sideboard for this matchup — it completely shuts off all their reanimation spells and must be countered or removed for them to function. Keep Force of Will in your opening hand aggressively and use Consign to Memory as additional free countermagic for their Dark Ritual sequences and reanimation spells. Your combo is also a legitimate racing plan: a turn-two Emrakul off Sneak Attack with an extra turn trigger just wins regardless of their board state. Prismari Charm and Spell Pierce are cut since they're too slow and unreliable against their free-discard, Dark Ritual-accelerated opening hands — prioritize Force-backup hands over interaction-heavy ones.
