What are your thoughts on Fellwar Stone in place of Darksteel Ingot, or Maelstrom Pulse instead of Beast Within (or in additoin to)? Moltensteel Dragon probably deserves a spot in here too. Moltensteel + Skittles will usually take someone out. I can't imagine you needing more land filtering, but Expedition Map may be worth considering too. A friend of mine runs this general also, and he has several spells to get the dragons back from his graveyard including Animate Dead, Karmic Guide and Necromancy.
