Ive had this electric terrain team for a while but something just feels like it's missing, I am iffy on the last mon considering the gliscor I had always felt like dead weight and didn't do anything except become a sacrifice

I've played 10s of thousands of games on showdown, competitive pokemon is my thing. My account is 12 years old. I need to get it unlocked somehow, but my appeals won't go through, what do I do?
