I'm not quite sure if my judgment is off, or if I was lucky, or if I'm a better player than I think. I cracked my 6 boosters, sorted it by colors, and just stared dumbfounded at the mess for half an hour. I had some decent red cards, but none of my other colors was any good. Some good creatures but very few spells. I decided to make my second color black because I got a Royal Assassin. I threw in pretty much every red card and added enough black to make a deck. I thought I was very short on creature removal, but it turned out to be just enough. The decks that I lost to and drew to were also red. Most of my wins came when I got to 6 mana and was able to play Warstorm Surge and/or my two Volcanic Dragons. My artifacts were very important for living to turn 8 later: Throne of Empires for free blockers, Greatsword to make little creatures matter more, and Manalith to help me get up to 6 and to help it be the right color.
I like playing in limited, where it's actually about creatures attacking turn after turn, rather than most constructed decks, which are play for a while until you get a gimmick set up, and then you either lock the board down or blow your opponent up with something huge.
