How did you get enchantresses costume!! What team did you have?

My team was: Carol, rank 5, rarity gold, level 36; Mar-vell, rank 5, rarity gold, level 28; and Beta Ray Bill, rank 4, rarity bronze, level 23. 

I barely won the last fight – Mar-vell was down in the red zone HP-wise and the only one left standing and he got a lucky hit to win the fight. 

Thanks for asking!
