Here is a video analysis on KR Challenger Riven one trick "pi9," who has peaked at master+ in 6 different seasons.
A KR Grandmaster decided to get the tips from this playrr and have explains everything from small details in laning phase to how to win the game.
It includes one NASTY trick in the beginning of the game to secure your lead at top, which probably works up to at least diamond in NA. Then it explains about how to snowball that lead that you got in lane to plow through victory. Most of the tips apply to top lane in general, which is awesome.
I hope you guys enjoy and learn something valuable from this. :)
