Oh crap, well at least I know about the two first moves locked in and only one new move this round, so I highly appreciate you letting me know on those. I removed all but one new move for each Tandem with that in mind.The Pokemon choices are incredibly inspired and I love the concepts you are going for, but from my understanding you are only allowed a single new move this round, and all of your subs have multiple moves, so I think they would all be vetoed.
As for Dudunsparce specifically, Hyper Drill is definitely a redundant move. Dudun's offensive stats are so wide there isn't any reason someone would ever click Hyper Drill unless it's a Coil set, and like I said at the start, the first two moves are apparently locked into place, so it's odd. (I personally think Roost is a much better move to add, low-key a disservice not to have it here, locked in or not.
I added Roost as Dudunsparce’s new move in place of all the other new moves per your suggestion.









(sets fixed, outside of Zam who was already fine)
