Roshi, mei, fuguki, water main 321 1/4 2 summon that chases high float to low float twice

Roshi, mei, sage naruto water main. 321 1/4 2 and any summon which chases knockdown(probably katsuyu)

Just one thing more, putting a barrier breakeer and barrier ninja is a irony itself, both mei and roshi have their own set of teams but never seen them together, but the fuguki one i mentioned could be worth a try with water enhancement passive
