Pokémon X and Pokémon Y

Thanks for the site; didn't know about but I'll definitely make use of it.

 Spoiler

Originally I did have Dazzling Gleam there, but I had a lot of trouble deciding between that or Destiny Bond. The only reason I went with Destiny Bond is because I figured if Mega Gengar couldn't take the opponent out with its immense S ATK stat and Speed, that I could at least take the opponent down with me, but you make a good point.

*headdesk* I feel dumb. The main reason I went with Clefable over Sylveon is because I accidentally mistook Magic Guard as Magic Bounce. Overlooking things again, I now realize they are, in fact, quite different. Well, I'm most definitely going to work Sylveon in instead.

The reason I had U-Turn for the final slot was because everyone else I talked to and other articles/guides I've read about Greninja all suggested that it was essentially mandatory to keep momentum going and to preserve Greninja. Before that, I did have Grass Knot and used it quite often and it definitely gave great coverage.

As for Talonflame... my mistake again. I used the wrong Talonflame set-up from my documents. (I keep all this stuff in documents to stay organized, but I also my friend's stuff written down, as he refuses to ask anyone else for help.) My EVs are your typical DEF 4, SPD 252, ATK 252.
