Okay, you have 2 dragon type pokemon, this can be a bit difficult if you were to go against someone with a decked ice type team considering you have Venusaur as well. Gladly Tyrantrum is a rock type so he can surpass that area, but I would replace Venusaur, I know the 3 starters and their mega evo's are super cool! Yet they dont exactly meet many of your qualifications I would consider adding a Gengar, taking out Goodra and adding Garchomp. Garchomp in mega evolution has an amazing attack that blows it up to into the top 100 at the 2nd best in the attack stat range. I can give you even better information, considering I have a pokemon trade shop and I own many shinies and I have been in tournaments. I can give you deeper advice if you e-mail me with a list of their movies, natures, etc. email me if curious
