Karma and Morg beat most midlane matchups solely due to their oppressive early games but fall short to any decent midlane picks in that they don't have as strong of late-games due to their hugely lacking DPS as well as their unreliability/need to get close. The only good midlaners that need to get close are exceptionally tanky or strong mobility.
If you can win games at the laning phase, go ahead and pick something like Morg or Karma, but in most high elo games you'll find it's better to pick champions that don't need to engage for their teams.
That is, until Ardent Censer Karma came up. Now you just press E on your AD and laugh.
I wouldn't say they fall of lategame. All the assassins fall of lategame so that wouldn't matter. And any of the mages will still die if they get hit by her Q.
A full AP Morg can Q you for about 1k and her W will tick for roughly 300. Doesn't matter if you are Ahri to Lux, they will die from that. Sure they can dodge the Q, but I mean Morg can basically do the same to them. Lux has no kill pressure if she can't Q you, and Ahri if she misses her charm can't really kill a Morg since her shield will absorb majority of her all in and Morg Q will be up before Ahri E.
Not to mention they bring something to the table that Ahri or Lux can never hope to achieve. Later in the game they become high priority 2nd support targets. A Morg can still do her support job as AP, while still be a threat to everyone in front of her due to her damage. You gotta burst her or she will kill people, but you gotta kill the ADC or they will kill you, but can't kill the ADC easily when Morg can protect them still while killing you. Ahri is predictable in what she wants. She wants to get a pick on someone alone or out of position. In a teamfight she stays on the outskirts since if she goes in the middle of it, doesn't matter how many dashes she has, she will die. Lux basically has to land Q to kill people, otherwise just sits back and throws Es mainly which don't do much on their own.
And that is just Morg. Karma is even worse since her RQ can legit 1 shot you, super low cd Q. And she can still chain people and shield people galoore. Can't ignore her, but can't get the ADC while she is alive either.
