Hi, I’m just starting out and learning in Frontier Mode; how do I know if I have "ghost cards"? I want to enter the contest.

Thank you so much for the two cards—the gifts are wonderful. Can I use them to enter? I have two friends who play, and I’d like to know if I can play with them; they are beginners like me and are also in Frontier Mode using simple cards, just like I am.

Can we participate?
