Best to rely on the friend lead to speed through the fights like Lucky mentioned. You can lead with your STR Broly or Paikuhan and throw together a mono STR team that can link well with LR Broly which should breeze through every Quest stage.

Also, there's no reason to max out dupes of a card you own, not much benefit, either trade them or use them for potential unlocks.
