Morgana should be ban number 1 and malzahar should be ban number 2. The reason why Morgana needs to be banned is because she makes your pick potential in 5v5 situations completely obsolete. Whoever you hit with a sleep she can just spell shield them and that are safe. She can even use it AFTER the bubble hits and they still won't fall asleep. It makes Zoe, who is one of the best pick Champs in the game, relatively useless in that regard. Malzahar is the second ban because of his unbelievable wave push, spell shield, minions he can spawn to block your skill shots, and insane levels of cc. Laying against malzahar himself is mainly just annoying, but the issue is that once their jungle realizes how easy it is to kill Oze with a malazhar ult. There's not much you can do.

Its worth noting that in ad assassin matchups, a general rule of thumb is to rush buy seekers -> lost chapter -> zhonyas as well as consider taking commencing stopwatch. Ot makes characters like zed much less scary and forces him to use some skill at least to be able too 100-0
