I've opened maybe 30-40 packs and never pulled one. I have three now by trading away packs for them. The odds were far better. On the night ND was first available online I traded 9 packs for one, then 15 packs for a FA. I forget how I got the third one. I was trading for all the other EXs too, mostly only having to trade 3 or 4 or 5 packs for each of the other ones. Now I have at least three of each one. Opening the packs is a bad idea because the chances of finding one are slim. I probably traded away the equivalent of 70 packs but ended up with about 18 or 19 EXs from those trades which is way better odds than 2 EXs out of 36. The other cards in the set are useless anyway, except one or two of the rares like Guardevoir, or the trainers.

Other note - at the states tournament this weekend, there were two boxes of booster packs given to the winners that were opened and NO, I repeat, NO full art card was in either one! I know because my son had one of them. He did get a regular Mewtwo EX so we aren't complaining. But there is NO guarantee of a full art card in every box of ND. Unless they had differnet booster boxes for the prize winners. They were sealed in plastic so I think they were the same.
