The top champs out of lane to counter Ryze include Zeri, Ezreal, and Kai'Sa. These are all great at countering Ryze with win rates over 59%. Even if these Ryze counter picks are not taken in your lane, it's not smart to choose him into any of these matchups. They will usually beat Ryze.
Conversely, if the enemy team brings either Teemo or Brand, you should strongly think about selecting him, as he easily crushes these champs with win rates over 54% against both ofthem.
