Hey guys!

Round 1: Wait for their standard attacks (last one is Mei), use Mabui's and Earth Main's mystery on Madara, Madara's and karin's mystery on the right team (Ay, Minato)

Round 2: Wait (last one is Minato's mystery), repeat

These guys deal a decent amount of damage so good luck, you need a good amount of power to not die and beat it

At least no wave 2
