Greninja is good.(Better if you have decided to add Grass knot).
Crobat is Superb.
Golem: You may teach it Stealth rock.
Ampharos: Power gem will be better than rock smash.
Lucario: Great.
Chandelure:It is a monster.
Now suggestions, you need ice type mons or moves (cause: Dragons)
You can replace Golem with Rhyperior.
Consider steel moves too.
