Rakdos Reanimator is nearly identical to UBG Reanimator in gameplan — win as early as turn one by reanimating Griselbrand or Atraxa off Dark Ritual, Reanimate, or Shallow Grave. Endurance is the star of your sideboard here — flash it in response to any reanimation spell targeting a creature in their graveyard to shuffle their entire graveyard away and blank the spell at instant speed. Bojuka Bog is already in your main deck and fetchable with Crop Rotation — hold it to fire in response to a key reanimation attempt rather than proactively deploying it. Force of Vigor is brought in to handle Animate Dead on the stack at instant speed, giving you additional free disruption without tapping out. Sphere of Resistance taxes their Dark Rituals and Lotus Petals, which disrupts the mana efficiency their turn-one kills require, making it worth keeping all four copies.
