Whoa ninjas with Petrova-Carnival support xD
Baiken and Hustle are fine, but I personally I'd add a bit more draw power because strikes are gonna deplete you hand really, REALLY quick. A 1xCyber Brain, atleast.
I've always wanted to play a Yuunagi build. I'm gonna steal this, ciao xD

I once made a shinobi deck with yuunagi and stuff. and it was a flop >.>. but this build is pretty interesting with addition of petrova.looking forward to see it in action. "Time to modify my shinobi deck "

Did anyone even test it? Add a Cyber Brain in before you do.
