I am semi-excited to play this. It seems like a nice change of pace and I enjoy playing other formats from Standard (Expanded, GLC, and even the current "Expanded" in PTCGL), but I don't know if I'll stick with it for too long. It's almost certainly gonna be pay to win, and if not at launch then certainly not long after as with practically all games with in-game purchases.
Also I said it before, I'll say it again, I really wish they adopted the point system over prizes in the real TCG... I know it's been there since the game's inception, but it's the worst aspect of it (an extra level of RNG that can cost you games before the match even begins, even if you build around the mechanic and make your deck clunkier to try and compensate for bad prizing), and it's never too late with how many revisions they make (like changing tools to no longer be items), even if it makes some cards less useful or useless.
