Guides on IGLing and midrounding?

I recently saw a video by nitr0 about being an IGL and now I'm curious if there are any other videos similar to that

Something along the lines of:

-Managing risk of ult economy
-objectives and calling on specific maps
-certain information cues for midrounding

just mindread the opponents

Calling in silver is like trying to make 4 headless chicken follow u

Bump

I heard FNS tried streaming a midrounding guide

Any vods?
