Greninja is better with it's ha Protean and item Life Orb .Greninja should have ice beam over Blizzard beacuse of the accuracy. Garchomp is better with it's ha Rough Skin and item Rocky Helmet. Goodra item should be Assault Vets. Aegislash item i think would be best is leftover. Delphox item Salac Berry or Choice Scarf. Virizion item air balloon. If you need more help, just tell me and the set could be different to be a better team.
