For example, if I get the time to do so, you can design your own Pokemon card (of course, there will be limitations to this); by default, these cards cannot be used against others unless the ban list is set to anything goes mode. The more powerful the card, the more side effects there will be...
So, yeah, if any suggestions - let me know.
Edit: I have placed in two sleeves: Piakchu and Mew! You can have these instead of the boring old plain Pokemon card (though they must be unlocked first! Except in the beta versions)
