My five pokemon can already deal with all of those, and Latios is no problem thanks to Tyranitar (which also helps out with Cresselia quite a bit as well). Sableye can take out Hitmontop, Scizor, Garchomp, Metagross, and physical Tyranitars, while Togekiss can make short work of hitmontop and Scizor as well. Thundurus is easily taken care of by Tyranitar and Garchomp, while Sableye can help out by giving it the Lagging Tail. Hitmontop destroys Tyranitar too. Metagross is destroyed by Garchomp. Politoed an Rotom don't have any counters, but they don't pose any threat, particularly with Air Slash hax helping out where it can in every area. The only pokemon I think that I may have a problem with is Amoonguss.
