I don’t think you can make the deck meta, but Ninja is so close to being a good rogue deck. Hell, it was for a VERY brief time during Kash format.
The deck just needs an in-archetype ROTA. A way to get to Hanzo more consistently or a way for Hanzo to get an extender if you already have him in grip. And Notebook of Mystery DOES NOT COUNT. It’s practically useless on your first turn.
A spell/trap negate would be cool too. I get that giving every deck a solemn judgement is kinda lame, but Ninja’s whole gimmick is utilizing its. Ninjitsu Art cards and it would help the decks huge weakness to board breakers.
