no metagame decks use bench-sit lv x's. And AEN, any deck that has a main attacker (or something that's not claydol) with a pokepower uses 2 unown g. Poltergeist isn't hard to counter, just waste trainers when you need to. And to get around fainting spell you can use skuntank g, crobat g, uxie, shuppet (banette can be used as a mewtwo counter), etc. Another thing: you say it's a smart play: then why aren't top players running it? How many gengars were in worlds top cut for masters? Very little. Lafontes are easily the best in the game, yet do you see them running it? Professionals like Yamato, Itagaki, never play it.
