Commander EDH: Red Land Destruction

When we aren't playing RPGs, we play Magic the Gathering. Specifically, we play Commander/EDH format.

I like to make decks based on stuff I haven't tried before. This deck is solid Red, a color I rarely use, and based on land destruction, which is vilified and hated by basically everyone. I've used it three times; each time with a different Commander. The first time it did okay, but I wasn't paying attention and used a terrible card as my commander. The second time I was the first one out because everyone was scared. The third time I won by using Obliterate to clear the board then pecking the shit out of the other players with goblins because I could get them out before the other players could play anything.

After each time using this deck, I've modified it based on the play experience. This is the most current iteration.

I don't want the land destruction element to be obvious, and I don't want to destroy my own lands except as a last resort. Cards like Stone Rain or Rain of Salt are too limited in the EDH format so I removed them after the first go around with this deck. This is not meant to be a competitive deck (I just play casual with friends), and we don't pay any attention to ban lists of any sort. Also, I have a very limited budget (I got Wheel of Fortune out of a booster pack when Revised was new).
