Looking for a Mid

Currently, have a team that has been playing together for 4 years. Recently our mid lanner hasn't been able to play and we are looking for someone to replace them.

We need a player who mains mid that has a wide champ pool that is Gold or Plat elo in flex. A person who is chill and none toxic who doesn't rage (don't think they exist lol).

If interested add me in game IGN: Thè FIash
