Hi, i am a recently returning player from many years away.
I have 6 hydreigon i evolved from the event. Currently, I have 3 with bite and 3 with dragon breath. All with brutal swing. Should I use fast TMs to get bite on all 6 or leave some with dragon breath?
I feel like I would just want all of them to have full on dark attacks. Like dragon is strong against other dragons, but I am not sure i would want thia against other dragons since it would also be its weakness, right?
Edit: I only pvm. Haven't touched pvp.
