Hey, since you are playing red, i would add Lightning Bolt or even Incinerate or another random burn spell. If your Master is able to hit you can just finish it with one of these and you dont have to wait for the next turn to attack. Also they add up to your creature removal spells which is nice to make the master hit.
Good luck :)
I hadn't thought about Artful Dodge at all. I don't know why. If I add lightning bolts and / or artful dodge, which cards should I remove?
