Over the past yearaggressive decks have begun to dominate the tournament scene. Similarly, in the United States Regionals, aggressive decks were a significant force. The three decks that were most highly represented in the Top 8 of U.S. Regionals were mono-red, Suicide Black, and white weenie, in that order. Together, they won roughly half of the qualifying spots for U.S. Nationals.
Aggressive decks are extremely focused.
Their goal is to kill opponents as quickly as possible, usually by summoning fast, efficient creatures early in the game and overwhelming all opposition. Focus on this one goal when building an aggressive deck. First, build for speed. The focus on killing an opponent means that the first three or four turns are the most important. Therefore, it's extremely important that the opening draw be as consistent as possible.
