LF Support/mid main to duo with

I have only 2 champs i ever play when im try harding and they are

i mainly play twitch in the jg it works well for me. Then ill adc as draven but, i can adc as twitch its just not nearly as good as my twitch jg. If you're a mid main it would be nice if u knew how to freeze so i can just non stop gank the mid laner

Support champs i really like are: Thresh, raka and lulu but i prefer a thresh over those 2. Currently im silver 3 i have a 67 percent winrate with twitch and a 55 percent with draven. I've been gold 5 before however, i have gotten to p5 mmr with a 70 percent winrate on twitch and overall if that means anything.

Thanks!
