LF Active Serious Mature Team for 5's/3's Gold/Plat player

Just like the title says. Highest soloq rating Gold IV too lazy to climb at end of season. Highest team rating plat V in 3's. Id prefer mid, support for 5's and bottom lane for 3's. Looking for maybe gold-plat team that are active every week and like to play for fun and learning but serious and wants to climb. Pref 18+ players can use voice chat. Send me msg in game.
