Cave 23 Boss Fight

oh well, unluckily I'm stuck at this pesky last caves level. Actually, I tried two or three team combo without any fortune. I'll try again in a fare hours' when the strongest among Friends birds are available again.The weakest points today have been the pack of a plausible strategy to take care of the strong foes. They do both mass damages and individual damages. You cannot concentrate only on the big Boss because of the recurring drones and 140k Life points are really A LOT.Samurai, Princess and an additional beater is a Good combo but you Will bè quickly overwhelmed. Maybe Rainbird and Samurai could balanced enemies' rushes. Druid and Wizard and Samurai seem quote strong on chart too, but I have not tried this team yet.Maybe I Will bè able to defeat this Level only when my GROUP mastery levels Will bè higher than 75.What do you think?
