Artwork - I find it from Chaotiki or DeviantArt
Card Template - King-Of-Craziness has a bunch of Chaotic related templates for the card outline, different elements, rarities, etc.
Editing Software - I use Pixlr.com , it's free!
It definitively is, specially considering that the game was being developed in 2007, which means its server most likely used old technologies, which at this were reverse engineered enough to be easy to work with.
Some useful details: those game files are used only by Microsoft's XNA framework, which means the game was coded in C# with .NET. That, by instance, means one most likely can decompile the game EXE using the application below:

After that, one could use that information to start creating a server. Beyond that, anyone can use an application like Wireshark to find which kind of requests the game is doing, even without decompiling the code, in order to make the server capable or responding them. Although, decompiling the code will most likely be necessary, in order to understand which kind of response the game expects to receive.

They have different sizes so be careful when you are ordering. Trading cards would use the smallest size which I believe is the 35 pt.
I'm really enjoying learning Godot right now. That's my choice of an engine, and it will fully align with my goal of the client and server being FOSS.
Some roles/jobs I can think of right off the bat:
* Artists for things like menu and UI resources
* Scanning and cleaning up cards
* Rules lawyer for reference when designing the rules engine
* Developers
Follow up: The only sites I could find the sleeves are Amazon and Shop2shop. Would you recommend these?
