Anybody know some good resources on how to improve in mid lane and climb fast? I peaked Plat 1 in like Season 7 maining Twisted Fate, then around Season 8 I quit the game for like 5ish years or so.

I was placed in Iron 1, and climbed to Gold fairly quickly only playing ranked sparely. I feel like I'll get to Plat again and get hardstuck. Any good pointers, anons?
