So if my X team consisted of...

Delphox- Blaze
Blastoise- Torrent (Mega Blastoise- Mega Launcher)
Pangoro- Iron Fist
Tyrantrum- Strong Jaw

Who should take the sixth spot, I've narrowed it to 8.
Talonflame- Flame Body
Pyroar- Unnerve (not sure which gender I like more)
Gogoat- Sap Sipper
Meowstic- Infiltrator (same problem with gender as Pyroar)
Aegislash- Stance Change
Clawitzer- Mega Launcher
Heliolisk- Sand Veil
Trevenant- Natural Cure
