Mind Blast

[Fenster]

Yeah but i like the draw a card to gain a small momentum and it could also trigger with jaces ereasures. But is it really better with Tome?

If you are willing to toss in some black, you'll gain access to:
{Glimpse the Unthinkable}
{Mind Funeral} <---(amazing!)
If you're using the crabs {Dimir Aqueduct} is a good choice too.

Personally, I wouldn't bother dumping mana into the {Echo Mage}. {Jin, Core Auger} is super high CMC so unless you have a way to cheat him out, I'd stick with more agressive milling tactics.
{Trepanation Blade} on your {Invisible Stalker} beats {Curiosity}.

Edit: I see you already have the blade.  Also, I've never had good experience with {Mindshrieker} outside of a top decking combo. If your primary win-con is mill, then 2 mana for one card is too slow. You can do better.

Note:  if anyone cares, this marks my 3000th post.  Sweet heavens!

The way I saw the archivists work was that you wait till you had no cards in hand, then both discard and draw as many as your opponent. Since you aren't really looking to mill yourself. (no flashback or snapcasters etc).
Jin on the other hand makes your opponent discard all their hand and allows you to have a full hand all the time, if not more than full with vesner's artifact.
The undead alchemist is fantastic against decks that are creature heavy, like a red goblin or a white weenie. Not so much against a blue delver/ snapcaster one tho. So sideboard would be great.
If you decide to spash black you may consider {lich lord of unx}
Or even {Geth, lord of the vault} himself

Christ those black blue ones are awesome! And Lich Lord of unx would work wonders with undead alchemist!
Ill keep this deck right now make some adjustments based your advice. Then ill make a "copy" off it and start working on eventuall black additions!
Thanks for the help guys
Ill post the update eventually

Take a quick peak at my black blue zombie mill deck (also in casual) for some card ideas.
My deck is not perfect (far from it) but its awesome when things start to chain up a huge zombie army. Plus I always want to put every great card I see. Lol
