1) This is what I want my team to Be is it a Good Team?

I really like your team, but I would have an Altaria instead of Aerodactyl and even a Flygon instead of Charizard. Both Aerodactyl and Charizard are bad against Water Pokemon and Charizard is horrible against Rock pokemon. I really like the Rayquaza, Latios and Salamence. And Dragonite is one of my favorite Pokemon, so I love the fact that you have him in your team. Other than that, I would have a Rayquaza, Latios, Latias, Salamence, Dragonite, and Altaria. (If I didn't have Latias, I would replace her with Flygon). That would be my team, but it's mostly your team. Anyway, no you cannot get a vs. Seeker in this game because you have a pokenav and in that pokenav is match call which is sorta like the vs. Seeker. And, it's true, Latios does have more Sp. Attack than Latias.

You realy are planning ahead of time arent you!lol.ok,that is a really good team but I sugest switching aerodactyl with a kingdra( you need a water pokemon)
I give it a 9 out of 10!
No versus seaker isnt in this game,but you do have the trainers eyes!
It all depends on how well you train your latios\latias,you can make there sp attack higher.
Hope I helped

Its bad because they are mostly all flying types if I were to battle you I could beat you with just tyranitar that knows rock slide hyper beam, thunderbolt and earthquake. You can't get the vs seeker I wish you could but you can't.
