This is a mirror-adjacent matchup where graveyard hate is paramount: Endurance puts their graveyard on the bottom of their library to stop Living End's suspend trigger from returning a full board of creatures, and it also resets your own Abhorrent Oculus discard fodder concerns are irrelevant since you want to strip their yard, not yours. Force of Vigor is mostly a sideboard card against their nonexistent artifacts/enchantments here and is a weaker inclusion, but is included as a flexible green card to pitch or cast off excess lands if needed; consider prioritizing Endurance copies over it if adjusting further. Dismember and Sink into Stupor are too passive against a combo deck racing to cheat creatures into play via Living End. Keep Force of Negation as your primary interaction to counter Living End itself before it resolves, since Subtlety can only target creature or planeswalker spells and won't interact with Violent Outburst or Living End.
