I see some major problems in this build.

Firstly, the mana curve is way too high, especially with the concentration of 3-drops. The majority of the time, you want most of your cards to be 1 and 2-drops with a healthy dose of 3-drops. The reason for this is because speed is basically the most important thing in magic. If you have an excellent combo to pull off, or a big critter to field, if opponent gets it done quicker than you it doesn't matter.

Next, DoR doesn't really have a place in here, as you aren't running any red. The 5 black cost is going to be a pain, even with the duel and fetch lands you are running. I know you like the idea of mirror imaging one back, but waiting around for the 5 black mana takes away any gain you get from his speed and power.

You also are running very little in the way of direct interaction, meaning dealing with stuff once it resolves. You have 9 counterspells (all of which cost 3, so they are slow), 4 sultai charms to murder stuff, and 2 unsummons. So, only 6 cards to deal with critters that have already hit the field. Meaning, if opponent fields something turn 1 or 2, (or 3 if he goes first), he will basically smack you to death for the rest of the game, which is the plan for around 66% of decks in modern.




The good news is, sultai is an excellent color combo for builds like this, if we can straighten a few things out.

The first thing we have to decide is if you want to make this a proactive or reactive control deck. Proactive control hits the field running, disrupts opponent's game plan, and grinds out a mid-game win. Reactive control plays for the counterpunch, holding lots of counterspells and murder effects, escapes the middle game unscathed, and then fields a win condition and sneaks a late game win.

Sultai is good at both, so which way do you want to go?
