Dies to Removal

Matt: How about Monastery Swiftspear over the Vexing Devil? The lack of trample on the devile makes it the weakest link in the creature base and with 14 sorcery speed cards and 12 instants it might gain loads of value from prowess triggers that your not really "working" for but rather have naturally. I have been very impressed with the swiftspear and often play it over my GG in the early game where the free lands might be detrimental to you.

IMO Vexing Devil is a bad card to play after turn 2-3 while Swiftspear keeps adding value even when you top deck one due to haste.

Oh, and hit me up if you need to borrow fetch-lands so you can swap the searing blood for searing blaze, it's just so much better if you have fetches in the deck.
