They're special cards only attainable during events. Not all of them are super powerful, but are still good cards. They also lose their damage bonus after the event.

Also look carefully at who you're choosing to fight in the PVP. You can tell if they have transcanned card(s) or not. This will give you an indication as to the strength of their deck. If they have an R3/R4 transcanned, they most likely have a good deck. If you don't see someone that you think you can beat, then back out and regenerate the list.

On the flip side, I'm sure paying customers get bored having to slog their way through too many easy battles with non-paying players that keep popping up in their queue.

I'm a non-paying player and I still get the same players popping in my queue that I can kill with taking damage. It can be quite boring.
