Wake of Destruction

I'm a total noob when it comes to Magic. My friends have been playing for a while and finally convinced me to give it a shot. This is my first deck (Second version), so any help would be appreciated, just don't be too brutal... The idea of the deck is to use your basic control cards in combination with cards that can be used to destroy my opponent's land cards. Also, I have no clue what to put in the side deck. What are some good options? I was thinking more control and some direct damage cards... Yes? No? Thanks for any and all input.
