Pls help
So... I started playing alistar and I'm kinda good at alistar but I'm not sure what to ban. I ban yuumi all the time because yuumi is so broken against alistar, but now I got lost in my head when I played against morgana. Against both Yuumi and Morgana I can't play. These champions outpoke me and I cant do stuff. Any help from higher elo players? Any tip would help.
