I think it’s gets harder every time you do the challenge 🤔 the first time I did it I beat it and got the chest using only level 7 and 8 cards without losing a single game, but the second time I tried the challenge I lost in the second match lol
Here,a strat: use 2 defenders,lucha and someone with a lot of base damage(volcano,cactarina etc)and then a killer.use lucha and base damage character for base damage and use your killer to frag people trying to kill them.
Dude you need to use Mimi you can do the wall and when they are trying to destroy the wall you can headshot them and it does so much damage and the opponents can’t get to your tower
I reached arena 13 in 2 days ! But i spend day 3 trying to get to arena 14 but it seems to hard sine i have 1404 base HP and the opponents i fight have like 1800+ hp so yeah ranking up fast is not the best strat lol
