No love for Ulamog, the Ceaseless Hunger? It's great in a mill deck.

Reasons I dont like Ulamog all that well:

He exiles, so no reanimation/copy shenanigans.

He's too expensive, and the ramp package in this deck is minimal.

The goal of this deck is not to win by mill, it's to incrementally accrue advantage. Mill as a win condition is an all-in strategy. This deck usually wins via combo or combat damage.

Is there anything from Guilds of Ravnica that you think would be a good fit yet or are you gonna just wait until the full set comes out?

New Lazav seems fun for the 99, so I might consider him for a bit of recursion. Besides that, most of the Dimir stuff is a bit underwhelming or too costly, which I mostly attribute to the focus on Surveil which is not what this deck cares about

Yea if anything I really like Dimir Locket, seems like a really nice include.

Thought Dissector, while hardly the most efficient card, fits both the mill and steal theme of Dimir. It’s one of the cards I run in my Torture! deck, for theme and flavor. +1 for the deck - your personal enjoyment of it really shows through!

Doomsday would be a nice end game card, in this deck ?

Why, pray tell?

What game-winning combo should I be fishing for with Doomsday for the win? What's the advantage of exiling my entire library in this deck?

I don't see any reason why Doomsday would be a good play in this specific deck, which is designed to win by attrition and not combos.

More like a last resort card. Y need a specific creature or spell or the enemy will win in a turn or 2, and y cast Doomsday to draw the card(s) you want and get the advantage. The downside is sure lose in 5 turns at best, but if you are at a point where you will lose the game anyway, then you have no other choice and y dont exile the enemy graveyard.Y set the draw for the next 5 turns and y win with mill(Consuming Aberration+ Rite of Replication), clone( Phyrexian Metamorph) or abuse the graveyard( Rise of the Dark Realms) of the enemy.
