How do you win against 3 healers comp ?

yeah sounds very basic but im really losing a lot of games because they drop Dagger or Sue and the characters are absolute immortal. i Try to use Squirrel Girl with the dmg in area but sometimes doesnt work because they literally overheal, other choice is Moon Knight but i feel he doesnt have a good dps (i mean you can absolute burst rocket and Jeff but not Sue or Dagger healing you know) and also Iroman but like i say

does anyone have a good strategy to kill ?? is like playing on hard difficulty
