Reshaper is a faster clock than Souls, but Souls is way better against removal of all kinds and is way grindier. I can think of Eldrazi decks that don't really play Reshaper (e.g. Bant) but I can't think of any BW decks that don't play Souls. Lingering Souls is absolutely one of the best cards in the whole format.
I refuse to believe that this deck is actually competitively viable. There's simply no way that 10 duals plus two Plains and one Swamp (do you want T1 Inquisition or T1 Path, bro?!) is gonna cast your Scullers when you want them. Can we get some of these shaky manabase players on this thread to tell us how the hell they are getting their Scullers out on-curve? Because it just seems like it must be pure luck to me. Or like Iguana, maybe they're GQing their own lands (in a build that's trying to get to 5 for Smasher, no less)?
The List has changed since then, as I did not have access to heath/caverns. Keep in mind - you only see the lists that are successful. Many iterations of testing occur, and usually, especially in a "young" archetype, the successful decks are ALSO experiments that happened to draw well/be played well/get paired against good matchups/any number of factors.
The most successful manabase for me has been -
4 Eldrazi Temple
4 Caves of Koilos
4 Concealed CY
1 Fetid Heath
2 Shambling Vents
3 Ghost Quarter
1 Swamp
1 Plains
3 Cavern of Souls
I would be willing to entertain the idea of swapping a GQ for a 4th cavern, and mutavault is another option worth considering.
I have had success with a few variants. Reshaper, like many here have said, puts you on an aggro-esque plan. I don't think lingering souls should be cut in favor of the reshapers, but I am not a huge fan of displacer. In my experience, displacer is usually a 3/3 for 3 that dies quickly, having little to no impact on the game. Of course, there are situations where it is AMAZING, but generally this isnt the deck to abuse the displacer. The taxes shell or Bant are better able to use the flicker as they can abuse flash(vial)/excess mana/better flicker targets.
That being said, many lists have done well with the displacers. I'm sure it is a solid option for those who prefer a longer game with a more controlling aspect.
