So I was thinking maybe you could use Ampharos (PT) and Miasma Valley (PT) together to create a power-lock deck (I can't think of that many decks built around {G} or {P} pokémon for powers (obviously, Uxie and Azelf are great exceptions). Since most decks do rely on powers, could this be a viable tech in any decks? Could a deck be built around this, maybe with Absol Prime (2 damage counters on opponent's basics) or a spread deck? Let me know what you think, because I can't see any problem with this being a successful rogue!
