[MunchkinMan]

I'm fairly certain that you read it on the other forum because I know we've covered that one several times. I'll confirm the opinions with official fact: You keep the card.

Though icons have been around a while (even before there was full-color Munchkin), it's always possible to find pre-icon sets. However, more often than not, if you have a card without an icon, it came from core set of that genre. However, there are links to specific card lists on the product pages for every set and expansion. Look towards the bottom, usually in first bullet under Resources.
