>>56529953I run a set with Curse that leverages use of any non-Ghost Tera to turn Dusknoir into a dual-purpose Pokemon. If I choose to pop Tera, I can use Curse to buff attack and defense at the cost of its already abyssmal speed, then keep building to a strong defense wall that can use Shadow Sneak for priority, and whatever other physical moves it might have. If I don't pop Tera, then I hit Curse and punch a hole in the opponent's defensive wall to either force a switch or chip their health over time. It's not the best set by any means, but it's probably the most successful I've been with Dusknoir since Gen 6, where I had it as a Trick Room setter instead. If you combo this in Doubles with like Cresselia or Farigiraf for Trick Room, or have a Coaching-user on-hand, this could prove more successful.
