LF team for flex bronze-silver discord?

I'm currently in promos for s4, I was placed there and I fell out bc I didn't understand my champs as well as I do now. I use Discord too and I've been playing mid and exploring top, I used to main support. My primary champs are Brand and Vel'koz mid, and trying Jax out top until Maokai gets a buff. Last season I was a s3 supp main and I got to my promos 3 times and failed :(. Hmu, I can play almost every day at either 5 pm PST (8 EST) or 7 pm PST (10 EST). Not most Saturdays for a while but yes for Sundays!
