Forum:Help Needed for trade binder

Hi, I was just wondering if anyone here knows good cards to get for a trade binder. (I'm on a budget and obviously not a big one). I plan on buying and selling soon so I was wondering what cards are worth good money in the game today. And also if you know any good card shops in New York that sell boxes cheap post them here as well please. As much help as possible would be appreciated. Thanks in advance.
