Yorick Mori

Why does no one play this champion? I never see him played and hes just so much fun. Like, you just zone your opponent in top lane and then destroy them at lvl 4 with a flash w e because you were poking them to death. Like iv'e never not gotten a kill at lvl 4 playing yorick. He's so rarely played that people dont know how to counter him, and once your fed off top lane you just tp whenever your team needs you, ult yourself or the carry and kick ass. Why do people not play this champion xD.
