Counter-picks

[Kaden]

Really it depends on the support more than anything else. If they enemy team picks something like Janna + Ashe, then you know they have no healing, relatively low mobility and their only method of disengagement is dependent upon a skillshot. If I wanted to counter that lane, I would go for Taric + Corki, probably. Ezreal or Trist would also work. You have a quick engagement and can probably drop whoever gets stunned.

Conversely, if the enemy team is running something crazy aggressive like Leona + Graves, you can counter with Soraka + Caitlyn because of their good survivability and ability to farm at long range. Alistar also works in place of Soraka, in that instance.

Bot lane really ends up being more about countering a playstyle than a champion's kit. You still want to take someone who compliments that as best as possible, but it's a more nuanced thing than countering a solo lane.
