>>20218544They're a great mechanic, even if some of them are absolutely broken. You've essentially gotten a bunch of new legendaries based on old mons that are mostly usable in competitive because even if their stats get ridiculously high, they can't carry an item or use more than one of them. I also like most of their designs, and the way that most of them work in competitive is more interesting than using a base form with a life orb.
