You can try some of the raid tutorials in the master link thread:
For what it’s worth, you don’t really need a lot of 5* heroes to raid successfully. My typical raid teams now are:
- color-stacked, 3 against the front enemy (Tank) and two against one of the enemies next to the front (Flank)
- 1-2 5* heroes (1 per color I bring), the rest 4*
- Two healers (preferably one that can buff attack like Boldtusk/Kiril and one that can either dispel or cleanse like Rigard/Sabina)
- One defense debuffer like Tiburtus/Grimm
- The rest are hitters.
With those types of teams, I can get up to about 2600-2700 cups without much effort.
