Necropolis Diablo

I know it’s long overdue but I have one path for Necro left and gotta go Jubilee and Elsa path. Team is Onslaught, Chavez, Guilly 2099, Kate and Wiccan. I think I’m fine with all fights but is Guilly 2099 enough to take Diablo and reverse his healing with her special 2?

Onslaught should be able to put in work with Despair from the Daunted as well.
