User blog:DidiSenpai/Need help for my new Katana World deck

I bought the trial deck and some booster packs from BT-02 and 03 and mashed it all together. This is new for me so I don't really know how to deck build a Katana World deck. I want my deck to be built around the Ninja Arts (I'm a ninja fan) What shall I do to make this deck less crapy?

Flag: Katana World of course ;)

Buddy: Phantom Ninja Kashinkoji <-- I might have to change
