I'm not sure I understand Mindcrank . If you're doing enough damage for that to matter, then you're going to win by damage not by mill. Right?

EXCEPT. Infinite combo with Duskmantle Guildmage ! Which would be mean but entertaining. Perhaps two of those as a backup win condition?

I like this suggestion! Mindcrank is usually used with Bloodchief Ascension for an infinite mill combo, but the Duskmantle Guildmage looks a little easier to pull off.

I really like that. Dusk Mantle could even trigger the combo off of Thought Scour !

Looks like you could use a few more synergistic counters. card:Jester's Scepter looks like entirely too much fun.

Puppeteer Clique is a very robust flier that does naughty things with your opponents graveyard. It would be a cool 1-of

If you are looking to axe Wight of Precinct Six , there are some really strong two drops in standard right now. Perhaps Augur of Bolas or even Black Cat ? If you want you can borrow my Snaps for FNM.

Sign in Blood is a great addition; solid card. But in a long game against a more traditional control deck, you are going to get crushed with card advantage. Perhaps Staff of Nin ? At least one to go with the Jayce on the sideboard.

So in a long game, I hope to aggro more than control, then second game I can side in Underworld Connections

Well, if you'd rather fill that spot with an aggro creature, you have some great options. Including

1. Jace's Phantasm
2. Knight of Infamy
3. Diregraf Ghoul
4. Vampire Interloper
