EP3-Card: Which pile for...'?' cards?

[PStar2cadet]

Question about after defeating an opponent.There's 4 piles of card packs to pick from...blue,red,green and black.I noticed most of the assist cards i got were from the black pile...is there a recommended pile for trying to pick up mainly weapons?and is there one for picking up mostly monsters?Do the colors of the packs indicate what kind of cards you'll get?Thanks for your time!

There are some great guides at a site called www.pso-world.com. One of their guides has the answer.
