I don't usually purchase cards if I already have them. In some cases though I'll make an exception. Here is an exception:

The top two I purchased from eBay, and the bottom two I received in trades. The most recent being today (the gray) from
The Troll. The two gray swatches are identical but the two whites are a different material, which is why I wanted them. If I happen to find any different colors of this card I'll be sure to get those too. Maybe a black perhaps? looks like I'll be hitting up eBay soon...
