Remember when we use to battle with our Pokemon cards and we would have to keep track of our health or power status? There are new trading cards out that will actually keep track of it for you. When you stack the cards, they will actually do all the work, the base card is your player card, and when you get attacked, you will place the action card on top of yours which will change the status of your player card. Can you imagine how much money this would make if it were Pokemon cards back when we were into that? I would be going ballistic for these cards! This new invention is such a great idea, because not only do people want to have these awesome cards, but people collect trading cards. So people won't just be buying only one of these cards, they will be buying a ton of them! Also, if this catches as much as Pokemon did, then all the kids will want some, and then their friends will want them so they can battle too. The new twist on trading cards, is brilliant. People with the old cards won't be able to battle against the newer cards, so they will have to buy them too. I think this idea will definitely make a lot of money if kids catch on to it and like it.
