Rate/fix my mtg deck b/u?

Profane command might be good here. But it looks like a pretty solid deck. But you could actually live without the blue. Stick in The Rack. And a few Funeral Charms maybe. You could have a few terrors in there for board kill. But I think you might like to put some answers against red deck variants. Like Dragon's Claw or Demon's Horn in the sideboard. Overall, this deck looks pretty solid.
