Alright so this is how it works. The first thing I noticed was a glaring weakness to mons like Drilbur in the sand which could sweep you effortlessly if it had Shadow Claw. Foongus is way too shaky of an answer so Shroomish is generally more reliable. Afterwards, I just renovated your Missy set since Taunt is important to get Rocks off the field (which you don't have a way of getting out), and it is full on offensive. Drifloon is an important Late-Game Cleaner to your team and gives you potential to wreck through teams given the correct time. Scarfed Murkrow can go around Spamming Brave Birds and hitting oppositional Steel-Types with Heat Wave. But with Magnemite support, Murkrow can just Brave Bird shit. Timburr gives you a strong answer to opp Misdreavus and +1 Scraggy if Murkrow is too easily worn down. Magnemite set was just switched Magnet Rise --> Thunderbolt since it can be more helpful in occasions. You can change it back tho.
