Looking for support

Need someone that can stay calm for 1-2 hours and that play's well so I can lighten the burden of the average player we are going to get matched up with and have a better chance of winning the majority of games. Open to all champions you would play secondary role anything you want, most important part is be able to shut down negativity in the chat defend yourself with gameplay actions, no typing anything back unless it's something like you keep typing negative comment's in the chat after a quadra or something to make them realize they are getting reported, so they stop typing and play better.
