Grixis Reanimator aims to dump Archon of Cruelty or Abhorrent Oculus into the graveyard via Faithless Looting and Psychic Frog, then return them with Persist or Unearth for game-ending ETB effects. Hold Force of Negation for Persist and Unearth, and deploy Endurance at flash speed in response to reanimation to exile their graveyard before the spell resolves. Tishana's Tidebinder comes in specifically to counter Archon of Cruelty's triggered ETB ability if a reanimation spell resolves through your counterspells. Post-sideboard, their Damping Sphere severely taxes cascade chains — Force of Vigor answers it for free at instant speed before you go off. Fire/Ice is too low-impact against their large reanimation targets and comes out to make room, while trimming to two Subtlety is acceptable since Endurance fills the flash interaction role.
