Definitely the new deck to have. If you really want dragons you should splash green or red to get the respective legendary dragons instead. I'd also suggest adding counterspells and removing planeswalkers and/or creatures...

Thanks se576, what counterspells would you suggest?

Disdainful Stroke in main and Neutralizing Blast in side. But are those Dissolve new? Shouldn't need much more than 2x Disdainful unless others disagree...

Two Disdainful Stroke is enough in my opinion, you got to watch out for Stain the Mind though, any of my friends that run black always hit my Hornet Nest or Whip of Erebos in my Soul Whip deck. Now that I think about it, Stain the Mind would be a nice sideboard card when playing with friends.

I would put the Jorubai Murk Lurker in the sideboard against red aggro decks - against some matchups it's excellent but it can fail against many other matchups.

How has Annul worked for you?

shepherdofire, it work much better than what I thought it was going to. Every time I boarded it in it managed to take counter either an ascendency or a siege. I really only expected it to take up room in my sideboard and/or hand (like most everything else in my sideboard save Bile Blight and Despise) and it worked out really well for me.

I was thinking of using it but everyone I know says "it's not for your deck". I have a blue black mill deck, if you could, can you look at it and tell me some control spells I should add.
