try going to "courtside" on saturdays after lunch, it's on the 2nd floor of robinson's galleria, a mall located on the ortigas business district. a lot of collector's converge on that shop to buy, sell and trade. another option is greenhills. a commercial area about 2kms away from the aforementioned mall. i'm not sure how many card shops are located in the area currently (but there should be a handful) since i've been in the US for quite some time now. hope this helps mate!
