I know this sounds dumb, but I honestly have no clue how to play this game. I know the very very basic rules of the game, but there's still a lot I'm unclear on. I clicked on this link from Yugioh Card Maker, and I know that Yugioh is based of of MTG, but I still don't really know much. I think that there should be a topic that teaches you the basics of MTG along with a couple OCG terms. I think that this would help a lot.
To be honest, if I knew more of how to play, I could actually make a couple cards. Just saying.
