>>14499928I can see entire teams being based around checking/countering Megas. Personally, I don't like them because the majority of them just seem excessively strong. 170 base attack/sp.att and 150 base speed just seems like GF was TRYING to make pokemon that would break the entire metagame.
Either most of them will be banned to ubers, or the OU metagame will focus on bringing the right mega to the battle or losing.
