Pokémon X: Victory 1

I've got good news, everyone!  I've finally defeated the Elite Four and their Champion.  Also AZ. 
I defeated them with a team of entirely Generation VI pokémon:  Meowstic, Gogoat, Hawlucha, Barbaracle, Doublade, and Greninja. 
Now, I'm setting out to defeat them again, with a team from each generation.  I'm also imposing a few other rules for my teams: 

• at least one mega evolution on each team
• at least one Eeveelution, if that generation has any (none for III & V)
• preferably, at least one pokémon that I'm using because I like it, rather than because it's "good"

However, before then, I'm going to finally catch pokémon from my Friend Safaris.  Specifically, I'm seeking females with Hidden Abilities.  I'll say this:  Meowstic's Role Play move is incredibly useful for this purpose.
