Okay, I played it, I'm at 7-0, I played against high ranked players so I grew fast the ranking (something like 2.2k glicko˛ but that's not relevant).
So, I played against decent player, and I found that Lucario was the less useful, BUT his priorities were definetly life saving sometimes.
I think this could be could to switch him for another Steel with a Priority. I'm not sure about Gyrados aswell, I think Mence/Dragonite are just better at the moment, but the neutrality to Ice was cool.
I'll wonder and give you my opinions on the possible changes later :p
But the team is fine ! Red Card was not useful at all, I think Rocky Helmet for some damages and to beat stuff spamming Rapid Spin could be better.
