Im a Noob Chip Zanuff

I got placed in the lowest rank possible as chip zanuff lol. I've gotten to bronze 2 now.

Can someone tell me the stuff I need to know to get to plat level?

I know a 5c.s mid screen combo and a wall break one.

I have know idea how to use rope. But besides that. What should I be doing and how should I start doing it? I kinda understand fundamentals (dlSF6) but not much of guilty gear fundamentals.
