Looking for Flex/Duo/Team

I am looking for a group of players to group with for Normals and Ranked. I've been playing League of Legends for 5+ years. I never really took the game seriously and have achieved Gold consistently in the past seasons. My level experience from greatest to least is: Support > Top > Jungle > ADC > Mid. I'm ready to up my game, but would like to be with some level-headed players to enhance my games. IGN: BlackPhantomDX
