Welcome to the forum, I’m glad you ask for help.
This is a very old thread. There is a teambuilding thread, where you can ask for help. Please post there and try to snapshot your team, and also snapshot all of your monsters that are 4-7 stars.
Alternatively to get instant help, you can send your screenshots into Discord PvP or PvE teambuilding section. The people are nice there and very willing to help.
This thread will be closed by a moderator soon.
Take care.
