I would suggest Psychic Strike as a good counter spell for this deck.

You should add Nephalia Drownyard as a mana sink as well as a land wincon that works with your overall strategy.

+1 for Harvey Birdman: Attorney at Law. I would put Ashiok over Tezzeret IMO.

Thanks for your thoughts so far!

Quicksilver: Tezz has proven very useful in this deck. I do really like Ashiok, though (he was originally in Stitcher Geralf 's spot). Any thoughts on swapping Ashiok for Szadek? The lord of secrets is kinda slow in this deck...

It still surprises me how few people use Aqueous Form a very powerful card when the demand is combat damage to a player. Very handy for Mirko and Szadek. I would go with Ashiok because controlling other creatures has a plethora of benefits.

Looks good! Szadek is kinda slow, but U/B gives plenty of ways to cheat him out. Maybe try Extract from Darkness ? It mills everybody, to boot!

Scalpelexis can mill a lot of cards if used right. I've seen someone Sadistic Sacrament all non-lands then swing with Scalpelexis for game. He works well with Fireshrieker too.

Just out of curiosity, why do you not have rooftop storm and/or grave betrayal? They seem to be good for your zombie mill theme. Also, Mikeaus the Unhallowed would be annoying to play against in your deck.

Thanks guys!

kiloken That's a fair question. The zombie subtheme is almost accidental... If not for Undead Alchemist and Gravecrawler it would matter less what type the other creatures were. The main reason not to include Rooftop Storm is that there are only 5 cards would enable.

I like Grave Betrayal , but feel it's too dependent on the opponent(s) for my tastes. This deck doesn't have much spot removal.

Mikaeus, the Unhallowed is worth considering for some extra resilience.

I feel Leyline of the Void is a must for any mill EDH deck. In multiplayer, if you group mill and haven't made sure to exile everyone's Eldrazi/etc, then all is for naught without it.

and Helm of Obedience could work. Especially when combined with Leyline of the Void

I just reasiled you don't have Archive Trap , an excellent combo with Ob Nixilis.

+1 for Harvey birdman ref.

Memory Erosion is good...also, how do you have a foil Spell Crumple ? a foil has never been printed....

Undercity Informer combos really nicely with Undead Alchemist

TwistedMoonlight: Sharp eye! I used "foil" to keep track of combo pieces. I guess I ought to clear them out now...

Mentock! The Mind Taker!

Jace's Phantasm is nice in a mill deck, and Wight of Precinct Six is good, but doesn't really work with Undead Alchemist .

Have you thought about putting in any Tutors to get out your win combos? Like Diabolic Tutor , Demonic Tutor , or Rune-Scarred Demon ?

Also Mystical Tutor and Liliana Vess

Needs Phenax, God of Deception and Eater of the Dead . You will mill everyone out at the table with this combo. Be wary of eldrazi.

Grindstone

Bonehoard is A MUST HAVE IN THIS DECK

Have you given Jester's Cap any consideration? Both as a way of drawing out land and stopping combos. Deadeye Navigator can also be good with Archaeomancer or any of your ETB-creatures.

Indigoindigo: I like Jester's Cap but cut it in favor of Denying Wind . Would you flip that? Bear in mind that big mana is pretty easy for this deck to hit.

Glimpse the Unthinkable ?
