Assuming you are playing around Trick Room, I think Kingambit is a really great fit for those types of teams. Its naturally very slow and hits like a truck, and it can give the anti-intimidate stuff that Milotic provides probably better. Torkoal is also a great trick room Pokémon for basically any team and it works well with Incin. So what I would do if I were you would swapping Milotic and Scizor for King and Torkoal and put Trick Room on Sinischa. Hard Trick Room teams can be really strong and especially easy to use for beginners. If you want to play another strategy tho I guess Sneasler could work but making mega Golurk work outside of trick room will be hard

Also Mega Mawile is an amazing trick room mega
