Man how do I play against this champion?

When you find yourself in this position, there is really only 2 ways people deal with this situation: Educate themselves on their kit, or keep crying about it and continue to lose when they don't need to. You wanna learn counter-play against a champion? The BEST way to do so is BUY THEM. Play them, learn how they work. I have done this with COUNTLESS champions, and it is because of that I rarely lose lane unless the other person is just fathoms better than I am. Try pulling off the same thing that the champion in question does that owns you, and see if you can replicate it. And WHEN you DON'T, pay attention to what the other person did. Crying OP is going to get you nowhere
