Actually I've yet to test Nefarox (in any deck) as I currently don't own any copies of him. I'm intrigued to see how he's trigger for attacking alone will work.

Actually I've yet to play Duels of the Planeswalkers 2013. I pulled a lot of common and uncommon exalted cards at the M13 prerelease and thought I'd try making a deck around it for standard. I'm sure I could make a BW Modern deck based on exalted that'd work, let me think on that and get back to you :p

I've posted quite a few versions of Kokusho Nuke. Hell, it's one of the ways I win with my Dragonstorm deck :p The one I'm working on now is a modification of the Spirit tribal deck I made that had Kokusho Nuke as a win condition.

I really tried to find something to suggest for this deck, but the only thing I can think of is to replace the Shrivel in the sideboard with Cower in Fear. it costs one B more, but it's an instant and only affect the opponent's creatures.

Earthcraft is legal in Vintage, but I don't play that format :p

And who's Sensei's Divining Tops are you going to use? Especially if I end up using mine?

Firstly, nice to see you haven't given up :D
I'd like to suggest something for this deck, but unfortunately I'm not too familiar with cards pre-8th Ed :|
I must say, after reading Blood Artist, I mite just add it to my Kokusho nuke deck I'm working on that uses Living End / Living Death (I forget which one) to put all 4 Kokusho into play from my grave, the "sacrifice part will cause Blood Artist to make the opponent(s) lose a lot more life :p

"Unbeatable" token based deck, meet my friend - Stronghold Discipline (I got a deck based around that card).
There are no "unbeatable" decks in MTG, but there are some nasty, tough to beat decks.
That being said, this deck isn't too bad, I'd like to see how it runs.

That is pretty much the idea of the deck :D
There is a little trick to it though, playing with the deck I have to be careful not to give creatures too early, else I'll lose to them attacking me (this has happened a few times). There is a down side to this deck, I don't block often, so I take a lot of damage early game. But as long as I'm on more life and / or have less creatures than the opponent, I should be able to win off of Stronghold Discipline :p

Silent Arbiter is a nice addition. Just a note, I'd not run more than 2 Cathedral of War because it enters the battlefield tapped.

I'm busy designing a reanimator~ish spirit deck. My deck's main play is to use Lifespinner's ability (Bloodghast works awesomely with it) to fish out my 1 Iname, Death Aspect. Then with Iname's ability, I put all 4 my Kokusho, the Evening Star into my grave, then cast Living End or Living Death for the win :p

A note on Bloodghast, Verdant Catacombs works awesomely with it. If you do add the Catacombs, another land to look at getting is Overgrown Tomb, it's both a Forest and a Swamp, so it's a legal 'target' for the Catacombs :)

Not sure if you know this, but the banneret's ability does lower prowl costs too, so I suggest taking the banneret up to 4x.

I share your concern on the restrictions, but I do like Dawn Charm's versatility. I use it as a sideboard card in one of my decks as an extra 'fog', but I've found the other affects useful too.

I'm thinking there's too many lands in here. Maybe drop a few to add in some off colour legendary spirits to search for. Maybe Kokusho, the Evening Star? You don't need to run its colour as Lifespinner puts what it searched for directly onto the battlefield :)

I'm not sure if you know this or if they'd fit this style of deck, but white does have some counter spells:
Mana Tithe
Rebuff the Wicked
Dawn Charm
Lapse of Certainty

Living End / Living Death could be a good card for if Mortal Combat doesn't work.
With the Lifespinner searching for it, Iname, Death Aspect can be taken down to 1x, I've found that more than that is a waste.

Iname, Death Aspect could help achieve the required number of creatures in the graveyard for Mortal Combat

You know, if you got dual tribal Giant Warrior, you can use Brighthearth Banneret to help make the Giants even cheaper.

Haste actually sounds like a VERY good idea.

Just remembered another "bomb" you could add - Blood Artist + a sac outlet. I've lost a match up because of a combo of Blood Artist and Day of Judgment in a token production deck:|

One card that may be an exception to that "rule" is Isochron Scepter's copy may count as it says "...you may cast it...", so you cast it :p
