i hate cocomambo.

i genuinely need help because i cannot beat cocomambo on extreme mode of guild battle for the life of me. no matter what i use and how much brute force i put into my team and builds it doesnt work and he keeps on healing faster than i can deal damage ive tried putting in some niche supports such as mint choco to help my wind archer instead of mystic flour and everyone in my team died in <10 seconds literally who should i invest into in order for me to beat this stupid thing.

(feel free to ask for additional information i dont know what else to add lol)
