Now, I have 2 teams looking at your ninjas.
I still use these 2 teams, mostly the full Jin one.

For the full Jin team, Its a guarantee 30 hit chase for Roshi if your opponent have 6 units
But, sadly, this team pretty much dead if your opponent managed to immobile/kill Yagura, he plays the important part on this team

For the Mei and Sailor team.. You can't trigger Roshi's chase, but you got some proper heal and shield to make sure Roshi survive
