He has great range, great damage throughout the entire game, and bullying is easy with him as QWQ doesn't push the lane
There is a tiny risk, high burst/gapclosers like Riven and Irelia can be a big issue.
But thats very close to a skill matchup, so long as you don't waste your snare or get too close you are good
not to mention I've had my ass handed to me as Ryze a lot in lane, but it doesn't matter because once I get tear ROA and FH, I can still take on a 5/0 Renekton as a 0/4 Ryze by 28 mins
And because Riot purposely nerfed early game snowballing and dragged the game on longer because they thought it was anti-fun or w.e, I can always get to that late game spike
