I discovered fairly quickly that C and D are impossible.
Once you open you one pack, you want to see more. Gotta complete the set and/or get that rare card!
Besides, what if you get hit by a car and never opened some of the packs!
I opened 4 packs so far and I'm really pleased with the cards so far. Every pack had 6 regular cards and one special card. I had one particularly nice special card which has a nice sparkly star motive over a Tonchan bikini pic (#106). I'll take pics of what I got once I opened it all. Dig the quality too. These are the plastic-y ones, which I prefer over the cardboard variety you sometimes see.
Until then, this is a scan of my favorite regular card so far (#62):
(excuse the crappy scan quality)
