Okay, HELL yes, glad those Dudunsparce stats are real.
Okay, so this thing might actually be good with that bulk and 100 base attack with access to moves like glare and coil. Looking forward to seeing what its learnset is.
On a separate note, holy carp, Scovillain is going to be a nightmare to deal with on a sun team. It has just the right stats to be an insane spammer with moves like solarbeam, solar blade, overheat and fire blast. It's also near perfect coverage outside of dragon types too.
Orthworm seems to be... a worse steelix? Whatever it is, not that impressive.
Garganacl has some amazing bulk for a rock type, its stats are similar to Gigaliths, except for less attack in favour of more HP and SP Def, which is nice.
Brambleghast has me curious, it has a nice attack stat and speed... kind of a faster Trevenant? Poltergeist would hit like a truck with this thing.
