I mean every single version of Buu has had both, and we know he still has his magic, as it's been commented on repeatedly and used at least once (albeit in the future when he sets Goku up to fight Uub), so I don't think it's much of a leap to suggest he can still do either. However, if it's really that much in contention like, again, Bergamo's absorption feats are actually kind of terrible and there's no reason Buu can't just beat him up. Like the Trio were never a legitimate threat to anybody; they were jobbers with one decent trick amongst them, and they went down pretty much as soon as anybody put in any effort to taking them down. Pretty sure the joke of them all being wolves is that they are the tournament's Yamchas.
