Well, it looks like Ash and Greninja face several difficult challenges (Mega-Sceptile, Team Flare and above all. The Mega-Charizard X Alain) but at least the growth and development that have will be more interesting if one were to confront coaches random.
At least it is assumed that Ash, the League of Kalos defeat Shota (AshGreninja vs Sceptile) and then lose to Alain, I say if only have to Mega-Charizard will suffice to sweep team Ash (I beat Mega of a member E4) should not as costale lot of work if you want to collect 8 Badge
