I had easy access to a lucky egg, and I thought "well... why the fuck not?". Kyurem because he was the highest level I had during my first run of Black so I kept him with me post-game (also, he's my favorite gen V legendary), and Beartic because he's my favorite of the gen V pokemon, and he was my first to ever EV train seriously.
But other than that... there were my pokemon in Blue that I used the rare candy glitch on, if you want to count that.
