UBG Reanimator wants to slam Griselbrand or Atraxa off Reanimate, Animate Dead, or Shallow Grave as early as turn 1-2, so graveyard hate is your main tool to blow them out. Surgical Extraction can exile their Reanimate or Griselbrand from the graveyard mid-combo, and Tormod's Crypt resets everything if they're relying on Faithless Looting fuel. Warping Wail's counter mode stops a cheap enabler like Dark Ritual or Unmask before it resolves, buying a turn to race. Trim the slower Tezzeret and clunky Fleshraker copies since this matchup is decided by disruption timing, not board stalls.
