... why did they even bother?
Golduck is probably overall more useful in its ability and it is a "Stage 2". Omastar is more than likely going to be weighed down by ridiculously bad fossil mechanics (please please prove me wrong Pokémon Co) and is basically a "Stage 3".
As for " Gust of Wind" effects Pyroar probably does it better because it's more accessible AND fire decks have amazing energy acceleration, being able to attach 3 (or more!!) per turn. And Pyroar isn't limited to EX Pokémon.
Omastar BREAK should have been the regular Omastar IMO. The attack could have been WCC for 60 and restoring a Pokémon, with the ability Dangerous Tentacles. Might have been a little "broken" with Archie but you get my point.
I thought that like Megas, BREAKs would have got good by now. I thought basic BREAKs like Lugia were a step in this direction. Nope! Better luck next time!
As a side note, I'm hoping this leads to Kabutops BREAK but as usual.... ya never know D:
