DedWards

I can get Cultivates, but I won't use them. 3 mana cost is a bit much and I'd prefer to keep my lands in play.

To me, budget is a combonation of cheap ($) cards and what's easily available in my group. This deck costs about $9.20 at channelfireball (excluding basic lands). Additionally this is for someone else and I'm a bit of a cheapscate, so 'available in my group' is the option I'm using :p

Ja, when I noticed the number of Zombie token creators, I looked for things that affect token creatures and the first thing that came to mind was Intangible Virtue :p

Mentor would work nicely and sideboard does seem best. Maybe replace the Wurms with it if the removal doesn't work / isn't needed.

I actually have, but I prefer my choices as most have some form of combat evasion (flying or intimidate) :p

Lashwrithe is arguably better than Strata Scythe in a mono black deck.

Actually you won't need to use kill spells to kill the Kokushos. They're legendary, so the split second there's more than one in play, they'll all die and each one's ability for going to the grave will trigger.

Essence Warden is a faster replacement for Wellwisher, that's if you want to keep the lifegain. It's faster for to reasons - 1) It costs less mana, 2) it works immediately as it doean't nees to tap to attack.

If you want to rely on the Warcaller and tokens for the win condition, there are a few cards I can suggest:
1) Heritage Druid - This cards provides a MAJOR mana boost that can be used to kick Warcaller A LOT.
2) Bramblewood Paragon - Warcaller and the tokens are warriors, so they'd get a +1/+1 counter from Bramblewood and as long as Bramblewood's in play, they'll all have trample :p
3) Ezuri, Renegade Leader - if you do use Heritage Druid with tokens, Ezuri is almost a must. I've once summoned enough tokens in one turn with Heritage to summon an Ezuri, activate his built in 'Overrun' 4 times and attacked with 2 13/13 trampling Llanowar Elves :D

Is it weird that I understood Ambiguity after only reading it once?

Read my response to Odaru's comment further up

Although they're good in token decks, those enchantments are not needed in this deck as I produce enough tokens without them. Also their mana cost is too high and would disrupt the mana curve I'm aiming for.

I've never been fond of 1x and 2x cards in a deck unless there was search for them.

Blood Moon and Magus of the Moon would be bad to face off against with this deck's land base.

That may be true, but I already have most of the cards in this deck and the new player has the rest, so I thought it'd be easier to build this. And as she already plays bloodthirst in standard, so the idea is pretty much what she's already used to.

Ya, that card may be the single card that makes me turn this into a 5 colour deck :| And if I do, I mite use Desperate Ravings too, but then I'd have to revamp the entire deck :(

Well I'm just working off theory. I've put an order in to get the cards I'm missing, so I can only put my theory to practice when I get the cards.

I like the idea, just not too sure on all the 1x cards. I've never been a fan of only running 1x unless I have a way of fetching it.

Lol, I keep forgetting about that card :p

I like the idea you're going for. Here's some cards that (hopefully) fit the theme:

Corrupted Roots
Corrupted Zendikon
Corrupting Licid
Trigon of Corruption
Corrupt Official
Corrupted Conscience
Ertai, the Corrupted
Corrupted Harvester

Hope I helped a bit

I know this. She already has a bloodthirst themed standard deck. The problem is our group doesn't always play standard and she ends up using her only deck in our legacy matches. I'm trying to help her by designing a deck for her to use.

Sadly I need to keep Vigor and Dread at 4 each for the whole anti-mill thing to work. 8 Elemental Incarnations means that even if my hand is full of them, at least one will be in my library (max hand size is 7, 8-7=1).

I'm going to be rearranging the deck tonight to increase the number of cards in the sideboard and to lessen the number of cards mainboard. If I drop any card, Moldervine Cloak mite be first choice for that.

A friend runs a zombie mill deck. He's is mostly blue (the only creatures are blue) with a little bit of black and white for cards like Unburial Rites and that white one with a blue flashback that can tap 2 creatures (I forget its name). He's deck centers around Undead Alchemist and other mill cards.

Fun fact about Undead Alchemist - he's 2nd ability isn't only if a zombie causes milling, it's any form of mill that'll get you the zombie tokens :p
