I too am relatively new (stopped back in '95, picked it back up a few months ago).

I currently have a R/U deck that is Red direct damage, two Spawn of Thaxes (Thraxos?) for a finishing move, and lots of blue draw meta.

I recommend checking some of the decks other members have built and uploaded to the site. Lots of good ideas there.

hey guys welcome to DB :)
i like the idea of R/U decks currently using a budget build on MTGO
this is it if youd like to see
but as stated above best way is to browse the database :), some really good brews out there

My suggestion would be to visit the Decks and Deckbuilding Forum and read the sticky on the fundamentals of deckbuilding.

Tons of links to good stuff out there that will really help you get the ball moving. Also, it is important to figure out whether you want to build for competitive play or casual, as the latter is far more flexible and forgiving.
