Welcome, Chisairi - remember we were all newbies once. If you have a question, just ask.
Now, guys - when you're talking basics, you really should get to BASICS, as in the true CLASSICS. Bicycle Rider Back, Bee Diamond Back, Tally Ho Circle and Fan Backs. THAT'S where EVERY collection truly begins; those are the cards I've played with since I was a kid. You can branch out a bit and check out some of the other less-common classics from there - Aviator, Hoyle Shellbacks, even Streamlines. Streamlines are cheap as hell (only $1 a pack at WalMarts in the US), but they're actually pretty good quality.
With those decks, all fairly inexpensive and commonly found in stores all over the US, Canada and in some other parts of the world, you get your foundation and get to see the different types of stock, cuts and textures/finishes. (Well, Tally Ho is harder to find - it's a regional brand largely sold just in New York City and magic shops - but it's worth it, they're some of the best cards made.) Then, when people talk about something like CARC Professional Bicycles being traditionally cut and made on Bee casino stock in both Ivory and Air Cushion finishes, you'll have some idea of what that means. That's when you should branch out and buy the custom-made decks these guys are talking about.
Remember, you don't have to drive yourself crazy getting everything under the sun - that way madness and poverty awaits! Be fussy, choosy and particular, only purchasing decks that truly appeal to you. You'll save yourself a lot of time and money in the long run.
