Here is a Team for your Road to Top 10 Ubers which i recently started playing and got to around 1500 points quite quick, in a hand of a better player than me it can shine a lot so i hope you can make it work. :]
The Arceus SpA Invest gives you a 100% chance to kill offensive groudon with lots of hp invest. Roar on Kyogre helped me lots of times against Power Herb Geomancy Xerneas.
