Rouge also happens to be a shade of lipstick.
I actually like the way Pokémon's going with this. There aren't just decks where the T/S/S lines are the same; there's some individuality to each deck. It's becoming less focused on Pokémon that can do the most damage the quickest and survive the most hits, and more focused on strategies that more utilize one or two of those points- for example, most SP decks, despite not having great attack or HP, are extremely fast. MewPerior's pretty fast and deals lots of damage, but Mew just gets OHKO'd. It's the same for every deck, and in this meta, the variances are great. I think that's a good thing, personally.
