Ok maybe I do have too much time on my hands but has anyone else noticed that the card art is different on some of the Obsidian Squadron cards from other Obsidian Squadron cards? I noticed that some cards have asteroids in front of the TIE Fighter and others do not have asteroids in front of the TIE. I have 3 core sets and two TIE expansion packs. But I have 4 of each of the two different cards.

Nice now my OCD has to kick in and check for myself, but yes there are two different cards...

You are correct. The Tie expansion Obsidian Squadron cards have a slightly different art than the core sets. Good eye.
