I'm thinking to bring
Onslaught
Venom
Bullseye
Leader
mojo worked well for me.
Shathra can do it but a bit slow. Good on CMM and remember she can nullify on light ending combo
Kushala was great for my run
First off, you can't use Kushala for the villan run.
Second, the dude literally posted his roster and you still managed to say "Kushala".
I'm sure kushala worked great for your villan run.
I used Juggs on mine and he was great.
I'm assuming you're wanting a mystic for the unstoppable nodes. I was in that position too when i did my run, but I didn't bring one. I would suggest ranking up sinister, that's who i used for those fights, and he's really safe for the whole path. I brought onslaught for the rest of the fights.
I see you don't have apoc, and I didn't either, you should still be fine, it'll just be a little bit slower if you decide to run those two champs.
I used Juggernaut and he was decent for it.
Fwiw, Vega has a video showcasing Mojo in the Abyss Villains challenge.
