Do you have a reliable answer to Tyranitar? Especially Dragon Dance variants. You can only revenge kill (and that's presuming he hasn't used Dragon Dance), but other than that you haven't got a Pokemon to resist Rock-type attacks effectively. Stone-Edge is going to run through your entire team.
I suppose there's Toxic Spikes and prediction that could eventually wear down Tyranitar, but yeah...
I know it's impossible to counter Tyranitar 100% of the time, but I don't see how replacing Infernape with Hippowdon would hurt the team much. Plus, you can always take out Porygon-Z and add Blissey to the team so you have an answer to Heatran with Lava Plume. This would also add Stealth Rock to the team (if you chose such), and you can always give Cressilia Rest>Moonlight with the Aromatheraphy that Blissey could support you with.
