This will probably help more than a team rate. https://docs.google.com/document/d/1qYztMbBTY0qm4mFy1-66bafgsVQ2gkeErAO3QUghEBY/edit?usp=sharing

Answer 1

There is a lot to be improved.
1.Psychic on a physical mon? No. Replace it with Zen Headbutt.
2.You have no defogger.
3. Focus sash on Dusknoir and Leftovers on Jolteon? No way! Switch the items.
4.This team would fail immediately against the powerful pokemon in Uber, I recommend using other Pokemon. Like, Naganadel, Pheromosa, Kyogre and stuff.
Tell me if you have any more queries.
Hope I helped!

Answer 2

This team apparently is a trick room team, looking at the dusknoir, but it, honestly, sucks.
First of all max Spe EVs for a lot of pokemon is not conducive to Trick Room, and physical Dusknoir is abosutely trash. M-Gallade does not run mixed sets: even if you do want it to, don't run SD on a mixed set. But mixed set is trash, because you have no SpA EV's and I doubt it would help much even if it did.
I don't have time for more edits, hope this helped!
