Problems:
Is the Aegislash set good. Should I replace King's Shield with Automize?
Weavile can easily shred this team, which was the match I lost. How can I deal with Weavile? Should I replace a member that can check Weavile?

Looking for good improvements as this team has made it to 1500+ Elo. Thanks for reading!

Comments

I think Spectrier is too frail for Calm Mind, I personally use Nasty Plot.

If I were you, I would replace blacephalon with choice scarf chandelure. choice scarf makes up for speed and it has great s.atk. Just my opinion though. also If your mimikyu doesn't lose disgiuse before itself, it can OHKO weavile with drain punch (into 4 weakness, what do you expect?)
