My favorite three decks: Blue-Red 4-drop spells : This is the base archetype for UR, and is supported quite well Grixis Control: As the name suggests, this is basically just all the good Grixis removal and card draw combined, with some lands for good measure
It can protect valuable cards from black discard, and can combine with library shuffling effects to improve your draw (such as Thawing Glaciers, Flooded Strand, or Ramosian Sergeant)
The release of the decklists for the Commander format comes hot on the heels of the announcement of the next set, Shadows Over Innistrad (see "New 'Magic: The Gathering' Set Announced"), due out in April
Standard, on the other hand, is a great format for teaching new Magic players the ropes
That Gravecrawler fellows a busy body
Standard actually has a very decent Burn list shaping up for new Standard, and Pioneer, Modern, and Legacy are going to love it, too
