This deck is designed to ramp out your big Eldrazi cards early into the game -- it's possible to get Pathrazer of Ulamog out as early as turn 5, and Ulamog's Crusher or Artisan of Kozilek as early as turn 4!
This deck will not include the Eldrazi Titans, Emrakul, Ulamog, or Kozilek, because it is simply budget at this time currently -- eventually we will include those cards instead of the Overgrown Battlement's, and a few others, however for now we're using normal Eldrazi as they're still just as hard hitting if not as sticky.
The goal of this deck is to ramp up mana early in the game to get our your harder hitting creatures, such as Ulamog's Crusher, and Pathrazer of Ulamog. I included 3 full sets of Urza's Lands, making it easier to ramp up colorless mana, allowing you to get 7 mana by turn 3, and depending on your draws, 9 by turn 4.
The early goals is to try and get out a few smaller creatures such as Thorn Thallid's or any other suitable substitute, along with Wall of Tanglecord's to help you defend yourself from any creatures that they might throw at you -- the use of Thallids and Giant Spiders not only allow you to lay out some damage early, but it also helps you last longer in the game to get your Eldrazi out, which will hopefully happen by turn 4 or even 3.
And optimal opening hand is one with 1x Forest, 1x Wild Growth, 1x Urza's Mines, 1x Urza's Tower, and either an Ulamog's Crusher or an Artisan of Kozilek, and then an Untamed Wilds. This hand will net you the most mana and the biggest creatures in the shortest amount of time from my** playtesting and experience with this deck.
Turn one, you play your forest and then attach Wild Growth to it.
Turn 2, you play an Urza's Land, tap your mana and then play Untamed Wilds, and search your library for the missing Urza's Land you have and put it directly into play.
Turn 3, play your 3rd Urza's land, and then tap all of your mana for a turn 3 Ulamog's Crusher.
The best card to draw into after the previously stated scenario would be an Artisan of Kozilek, as you can bring him out on Turn 4 immediately following the turn after the Ulamog's Crusher comes into play, forcing your opponent to either come to a conclusion on how to survive long enough to draw into removal, or to lose.
**I'm sure a better player than myself can figure out a way to get more mana in the early turns with some other combination, but this one seems to be the best way with this deck so far, allowing for a turn 3 Ulamog's Crusher and a turn 4 Artisan of Kozilek; At some point, the Titans will be included in this deck, but for now a turn 3 Crusher doesn't sound too bad.
--> Any suggestions for this deck would be highly appreciated, however submit a reason for card swaps with the suggestion as I'm fairly new and might not see the value in certain card replacements! Thanks!
