i've considered this, but, i've seen Jace's Phantasm not get to be a 5/5 until turn 6 or 7. while at turn 4 Balustrade Spy will definently be a 2/3 flyer that mills every single time.

i would reccomend stuff like Dream Twist and Mind Grind

I think that -1 Death's Approach and -1 Thought Scour for +2 Mind Grind would be a good idea. Just one extra card draw and removal is not quite as good or necessary as you have 3 Grisly Spectacle .

Seems like a fairly aggresive mill deck, I suppose I'm wondering how you'll adjust with the upcoming M14 and M13 rotation in the coming weeks. Also why 3 Mind Drinkers? Yes he seems to be necessary, however he is legendary so 3 seems excessive.

it isn't that excessive, with my decks low creature count, the chances of him getting offed with a kill spell is high.

If your on a budget you could side out Snapcaster Mage for Augur of Bolas . Also, I'm thinking that Thought Scour should be replaced with Tome Scour when M14 hits.

I like it. My mill deck Your Library is as Empty as a Real One took a more cipher stalker route. Definitely taking out cipher post rotation. I like it.
