Rock Lock is BDIF.
Look at the past 2 US Nats. What won? Delta, then the year after, Mario. Both rogue decks at the time. Major decks were in contention, but the best players always go rogue and take it.
My list of decks that could take it:
Empoleon
Blissey variant
RockBand
Leafeon variant
Skittles
Mario didn't win U.S. Nationals, at least not in Masters or Seniors. Speed Spread was not a rogue deck either. It had been played and won States and Regionals beforehand. Underground, yes, as far as people not having a good list, but it was not a rogue deck.
Back to back posts merged. The following information has been added:
I don't think you guys know your history at all saying that rogue wins the majority of U.S. Nats/Worlds. Let's take a look:
2004 Nats: Gardevoir (Archtype)
2004 Worlds: Magma (Rogue)
2005 Nats: Medicham (Archtype)
2005 Worlds: Nidoqueen (Rogue)
2006 Nats: Delta (Rogue)
2006 Worlds: Mewtric (Archtype)
2007 Nats: Speed Spread (Archtype)
2007 Worlds: Speed Spread (Archtype)
If you think some of these weren't archtypes, you probably weren't really in the loop. They were in my eyes. Delta was the last true rogue deck to win either. It's been two years. If anything you could say that a stage 1 deck has won the last 4 largest tournaments in the World. That is pretty interesting.
