So I've got a booster box (small) and now have all the Arceus cards and the Lv.X
The only one that looks good for a deck is the grass type one and I'll be mailing that to my brother since he has two of them for his Ditto deck.
I got the new Croagunk's and I think they'll be good for my "Kings Of Fighters" Deck. It's a perfect balance between strong attacks and special conditions. Back in the day I used Brock's Sandslash often.
But I want to build a new deck and have no idea as of yet. I'm waiting for the HeartGold SoulSilver set to come out in Feb. so I can rebuild my Crobat deck using the Great Crobat. My decks usually revolve around special conditions or weird things that throw a lot of people off.
