Aegislash was a pokémon that I wanted to use since the reveal, even before it was known as one of the strongest of Gen VI. While I thought that Binacle was weird, Barbaracle is without doubt one of my faves since the moment that the evolution was leaked.
Roserade is my favorite Grass-type, and a friend of mine gave me a Lv1 Larvesta when I was starting the game. Gardevoir and Bisharp are big bros too.
This was also the first time that I boxed a starter (Fennekin), but not because I didn't liked it, was because I tried to make a more original final team. I felt guilty for boxing it afterwards, so I transferred Fennekin to my Omega Ruby when I started it.
