Hi! Yes, exactly.
Card Duel System and its Expansion Packs are sold separately. You can find all the information on our official website.
If you’re interested in getting the complete package, I recommend using our special bundle discount here:
https://undermax.online/undermax/Card-Duel/upgrade/
There you can purchase both Card Duel System and its Expansion Packs. The more you purchase together, the bigger the discount you’ll get.
Regarding your question about the pixel art style, the system gives you plenty of tools and customization options to work with, so ultimately it will depend on how creative you want to get with your design. But technically, yes, it’s absolutely possible.
If you have any questions or need any help, feel free to reach out. I’ll be happy to help however I can.
I’m sure you’ll really enjoy the system and that it’ll give you the tools you need for your project.
