I find it hilarious that people are hating on a deck. You talk about every deck that can counter NM but you explain how to counter that deck. It all sounds very simple with the way you describe it, but yet somehow NM isn't winning everything. So what should we do if a deck is played a lot? "ban Pumpkaboo, Joltik, and Lampent". That is probably the worst idea I've ever heard. They already banned Lysandre's Trump card so you don't decemate this deck, now you just want to ban cards to just get rid of the deck all together? Why not ban the staple cards of every deck? Ban Hoopa EX, it's not fair to be able to get out 3 EX's from one card. Ban Shaymin EX, it's not fair to be able to draw until you have 6 cards in your hand from 1 card. Ban Maxie's and Archie, it's not fair to be able to put a stage 2 from the discard pile onto your bench. It makes no sense. How about instead of trying to get a deck banned because a lot of people are playing it, you find a way to beat it? Just because you see the deck winning and placing in the top 8 of a lot of state tournaments doesn't mean the deck is OP, it just means a lot of people play it. A lot of people play it because it's cheap and very easy to play. If it was OP then everyone would play it. Right now there's just a lot of people that play it, thats why you see it a lot in the top 8. If a meta for an area is that deck, you're going to see a lot in the top 8 because the probability of that deck reaching top 8 is greater. For example, if 50% of a tournament is NM and the rest is spread out (8% this deck, 12% this one, 5% this one), you're probably going to see 4 out of the 8 in the top 8 as NM players.
I have a NM deck and it's probably one of the most consistant, easiest and cheapest decks I've ever made/played. I'm not playing it for states because I'm letting my nephew play it because I think he'll do well with it. It's not that I didnt want to play NM, I just didn't want a bunch of mirror matches because that to me is boring. I'm all for banning cards that completely destroy a deck (Lysandre's Trump Card), but I'm totally against banning staple cards that make a deck what it is.
On a final note, I can't wait for the new XY10 Mew to come out, because that is going to make NM that much more played. MUHAHAHAHAHA
