Use Groudon or Yveltal when playing Ubers. Have you really seen someone use dusk mane Necrozma in OU? Can you show us a replay?

Answer 1

While Necrozma-DM's typing lets it blanket check a large number of threats, it also leaves it vulnerable to very common threats in the tier, such as Primal Groudon, Ho-Oh, Mega Gengar, Yveltal, and Marshadow, due to its common weaknesses to Dark, Fire, Ghost, and Ground.

Source: Smogon's page on Dusk Mane Necrozma. I am not aware if all of these are available in the newest meta, I know Mega Gengar isn't, but the others should still hold true for Gen 8 if applicable.

Comments

Necrozma itself is banned in SwSh, so I don't think you need to worry about that.

I won't include these Pokemon. They counter it, but what if they run a Weakness Policy Dusk-Mane with Trick Room? Ho-Oh works because of burning with Sacred Fire and Yveltal (only if it Dynamaxes, else it can survive one Dark Pulse).
