GW Eureka Annihilator (A Post Rise of the Eldrazi deck)

[Kangaxx]

Well, I recently purchased a playset of Eureka at SCG.com when I caught a glimpse of the new creatures with the Annihilator mechanic. Annihilator seems to be the perfect mechanic for a Eureka deck to work the way it should (which basically just means winning). I've messed around with Eureka in the past and I feel that a G/W shell seems to be the strongest approach, for various reasons which I'll explain later. Here's the initial list.

// Lands
4 [ON] Windswept Heath
4 [A] Savannah
2 [RAV] Temple Garden
3 [TE] Ancient Tomb
2 [BRB] Plains
5 [10E] Forest

// Creatures
3 Kozilek, Butcher of Truth
4 Pathrazer of Ulmalog
4 [10E] Windborn Muse
4 [CFX] Noble Hierarch
4 [AL] Elvish Spirit Guide
3 [M10] Baneslayer Angel

// Spells
4 [LG] Eureka
4 [ALA] Oblivion Ring
4 [CHK] Ghostly Prison
4 [PS] Orim's Chant
2 [EVG] Harmonize

// Sideboard
SB: 1 [M10] Baneslayer Angel
SB: 3 [10E] Aura of Silence
SB: 4 [TSP] Krosan Grip
SB: 3 [DS] Trinisphere
SB: 4 [MR] Chalice of the Void

Try to ignore the "to get list" aspect of it if you can.

What makes the GW build stronger than other color combinations boils down to various reasons.

#1) You have access to Orim's Chant, which allows you to resolve a Eureka successfully.

#2) You have access to Oblivion Ring, which I realized was very good with the Eureka strategy when I noticed how effective it was when I was on the opposite side of the table facing against it with a different Eureka deck.

#3) You have access to Windborn Muse which helps with the overall annihilator plan.

#4) You have access to Elvish Spirit Guide which not only helps you get an early Eureka down, but also helps against Daze.

Other things which make the deck cool.

#1) Baneslayer Angel can be hardcast in the deck, if necessary. It's always good to have the large majority of the cards in a Eureka deck hardcastable anyway.

#2) Most everything else can be hardcasted aside from 7 cards. This helps the deck's consistency since it isn't always good for a deck to rely on one card. And the other aspect of it is that you can cheat any cheap permanent into play given the situation.

#3) Kozilek, can maybe, I mean maybe, be hardcasted in the late game, maybe against Landstill or similiar archetypes. Which can be a plus.

The premise of the deck is basically mana denial in the form of Annihilator creatures, and prison effects, as well as beatdown. This deck is basically a prison-aggro deck and it's a blast to play. I'm getting it built in real life since I already have the hardest cards to find for the deck (Eureka).

I'm open to suggestions and comments are welcome. I'm just eager to hear what you think about this particular interaction of cards. Let me know what you guys think!

EDIT: I'll keep adding content to this OP whenever I get the chance! :)

Content Update 3/31/10:

I want to take the time to explain some additional card choices.

Chalice of the Void - I usually side these in versus decks that like to pack stuff like StP/PtE. Obvious card subs.

-4 Orim's Chant
+4 Chalice
-4 Noble Hierarch
+3 Trinisphere
+1 Baneslayer Angel

This turns the deck into basically an Angel Stompy variant with a combo finish, which I really like alot. Versus stuff like Zoo and combo this should be the way to go.

MD changes: I have to include Emrakul. The obvious changes look like this.
-2 Kozilek
-1 Pathrazer
+3 Emrakul

Kozilek is good but Emrakul is better. The main reason I cut Kozilek to one and kept 3 Pathrazer is basically becuase while I enjoy having Kozilek, Pathrazers are better in multiples. This rule is generally broken when applied to Emrakul, which is such a beast of a card, I couldn't see myself running less than 3 total.
