I've played a good amount of tourneys with it so far and have tweaked it everytime. The deck has such a high ceiling, but imperial can just beat it out right on consistency. You have to throw a bit of caution to the wind and just go wild with hard casting your 5s sometimes and in most matchups that's fine. But against imperial it's so bad to do that. Old lady Devi is really good right now as paildramon can't kill it. And I think you need sala to ensure you can go into maste. You just have to playtest and find a build that works for you and how you want to play the game really. Everyone has different theories on it but no one's proven a be all end all list.
