Rakdos Reanimator is nearly identical to UBG Reanimator in game plan — it wins by reanimating Griselbrand or Atraxa on turn one or two with Dark Ritual and Lotus Petal — so the same graveyard disruption package applies here. Grafdigger's Cage stops all reanimation spells cold, Dauthi Voidwalker exiles cards as they're pitched with Faithless Looting or discarded to Unmask, and Surgical Extraction removes the threat after any disruption hits the graveyard. An additional Thoughtseize lets you strip Reanimate or Faithless Looting before they can set up, and Consign to Memory is a free counter for the occasional Show and Tell out of the sideboard. Daze is a liability because they can simply float mana off Dark Ritual through a land bounce, and Kaito is far too slow against a deck that's attacking you with Griselbrand on turn one. Your game plan is to keep hands with Thoughtseize plus Cage or Dauthi Voidwalker, then force them into a position where every graveyard-based line is cut off.
