I haven't played too much with Set 10 yet with the holidays and all. Hope to fix that this week. But I feel like the mastery forces your opponent to enter in on you otherwise when you enter on them, they're screwed. I like that aspect of it because the Styles I've mainly played like Saiyan would get wrecked against decks with tons of board. And while I love this game a lot of the times, it was just drop non-combats and pass and wait for answers on my end. Very boring.
Also, feel like DBZ players have never put more than 2-4 anger lowering cards in their decks in. There are a lot of good ones now so people should be running them especially blocks that lower anger.
Lastly, probably the easiest fix would be to make Blinding BAU or make Trunks level 3 only grab styled attacks.
