I don't know, I don't feel like the deck was ever meant to be based around ninjas. The whole point was getting out Dark Simorgh/Avian/Thunderbird lock as soon as possible and just negate everything the opponent does. Hanzo is just kind of a bridge to get a first turn Simogh and not let them set anything on their first turn.
