Personally, when it comes to building a team I choose the Pokemon I like. I'm not gonna add a pokemon in my team just because he is in the top tier list. As Sonata said make sure you cover weaknesses and make sure your Pokemons synergies well with eachothers. You can also practice in battle spot and play free battles to see it goes. Anyways i'm pretty sure you can make it work.
