If you can withstand 1010 round 1, try to kill or stop Mabui asap by round 2 before she infuses chakra. That means it will stop Mei to use her mystery.

This team heavily relies on Chakra, steal their chakra is the best way to counter it. High likely only 2 ninjas which are 1010 and Mei can do attack with their standards. Mabui and Azure would be on heal for standard. That would reduce heaps of massive damage from Mei in round 2. This is where (hopefully) you should turn your table in your favour.
