That's a great team! i'm using Blaziken and Aegislash too, and they're both amazing. just take into consideration that your Blaziken is too much PvP oriented so in a long game he may be hard to play with (healing, PP, etc.), and that High Jump Kick and Flare Blitz are pretty risky. You may want to consider using a wide lens instead of a life orb, and putting blaze kick instead of flare blitz. And in my opinion Greninja is not the best choice you've got. I think Gardevoir is a much better choice. And last but not least you need to remember that you can only get all of those mons in the last chapters. I can breed them for you though, as long as you get a froakie as a starter and trade one froakie with me (He's the last starter I need for my starters collection).
