Ok, I know about the WOC site and it has the symbols for exansion sets. However, we've recently been winning some "bulk" auctions on Ebay and have gotten some with symbols we don't recognize or aren't on the wizards' list. One looks like a circluar hubcap 1997 on the copyright. The other is a pentagram 1993-1998 on the copyright. They also have a sword next to the creatures power and a shield next to it's toughness. Anyone have any idea where these are from? Are they basic set revisions with different symbols?
