You need Scapeshift to get those 4 Cloudpost out on turn 4, which would give you 16 mana on turn 5.

Scapeshift is way too slow. Crop Rotation is a better option.

card:Thespian's Stage makes this 16 post.

I doubt very much that card:Thespian's Stage will be efficient. This deck is supposed to cast an eldrazi consistently by turn 4-5. If I have to waste turn 3 converting a stage, this deck slows way way down.

I'm being totally honest, wreckedd is right, Scapeshift should be in this deck... I'm not sure how you think it's too slow, but Crop Rotation doesn't seem efficient... It's your choice, but if you want this to work better then Scapeshift should find it's way in...

Crop Rotation answers Wasteland which is a common problem in Legacy. Scapeshift does nothing along those lines.

Again, I'm casting an Eldrazi turn 4 or 5. Scapeshift is just too slow by miles.

I still don't see how it is still slow... the only reason you gave is that Crop Rotation answers to Wasteland which for some players will not see play in a deck because it is expensive, and hard to get... You want an Eldrazi out turn 4 - 5 consistently, this does that, I am interested to hear other reasons why you think it is too slow. Also, is this deck even created in real life? Cards like Candelabra of Tawnos , Tropical Island and Show and Tell are quite expensive and nearly impossible to get.. I have experience with realistic Legacy decks and something doesn't seem right with this deck... I mean it's good, I'm just not confident you have all the cards for the deck... Can you see why I would think this?

No I have all cards except 2 candelabras and 2 trops. It is sleeved up and I've been using proxies and playtesting whether I want to spend my tax return finishing it.

I like it all so far. Why I won't use Scapeshift is that turn 3 or 4 that I COULD cast it, I could instead, be winning the game and setting up to cast eldrazi by casting my titan.

Primeval Titan is 2 mana more but more importantly if ramps me up to exactly where I need to be with no land sacrifice and also puts it in a 6/6 body.

I've found I only have problems facing Blood Moon decks and serious combo decks. And that's where i'm trying to figure out my sideboard.

Ok, now that I see it from your point of view I understand what you mean... And those Candelabra's are impossible to get eh? A friend of mine has been trying to get one for 2 - 3 years and can't find a single person with one... If you wanted to use a replacement instead of the Candelabra's, I would put Doubling Cube in... Another great card that has something to offer a deck like this...

Yeah : / Trying to avoid the $350 a pop from star city lol.

I hear what you mean... I would still add Doubling Cube though... It would be really nice in this deck...

4x Thespian's Stage for 16 post, just for the LOLs

No thanks. It's a bit clunky.
