First Magic Throwdown

Matthew and I fumbled through a Magic duel this evening using single-color decks (white for me and black for him) cobbled together from the small assortment of cards that we own. I'm not sure we got it entirely right from a rules perspective, but we had fun and I think we'll give it another go very soon. We both suffered from a glut of land cards and not enough creatures, so I think we'll modify our decks accordingly. Matthew also pointed out, rightly, that the black deck I built for him had hardly any high-powered creatures, so we'll need to rectify that situation as well. Why do I get the feeling that my Wednesday trips to the comic book store are now going to involve picking up Magic boosters along with my pulls?
