I do not understand what it involves? My son likes pokemon cards and magic and Yugioh. And this looks like about the same also the same as the steem cards where @kus-knee talks a lot about. But than a monster version. How can you play that in steemit? Here two people or more sit in opposite of eachother and they play out a deck of cards, where they let the strongest win, it is a bit of strategic. I would not mind to give that a try! or is this just buy a card on line and sell it ?
