Pauper deck doctor: Sultai Tortured Existence part 2

Last week I took on the mission to deck doctor a Sultai Tortured Existence deck in Pauper.

You can read the first part of this exercise here: http://mtgolibrary.blogspot.se/2016/06/pauper-deck-doctor-sultai-tortured.html

This week I played a very educational match vs GW Hexproof, also known as "Bogles"



After some discussion the brewer decided to delve ever further into Blue, resulting in the following deck list for the final week (next week):

Main deck
2 Fume Spitters
2 Arrogant Wurm
3 Basking Rootwalla
2 Caustic Caterpillar
1 Spore Frog
1 Grave Scrabbler
3 Werebear
3 Crypt Rats
1 Stinkweed Imp
1 Tilling Treefolk
3 Golgari Brownscale
2 Mulldrifter
1 Krosan Tusker
1 Gurmag Angler
4 Tortured Existence
1 Gnaw to the Bone
4 Chainer's Edict
2 Vessel of Nascency

3 Barren Moor
2 Bojuka Bog
1 Dimir Aqueduct
1 Dismal Backwater
4 Evolving Wilds
3 Forest
1 Golgari Rot Farm
1 Island
2 Jungle Hollow
4 Swamp
1 Terramorphic Expanse

Sideboard
1 Disfigure
1 Ghastly Demise
1 Diabolic Edict
3 Negate
1 Crypt Rats
2 Faerie Macabre
1 Snuff Out
1 Raven's Crime
1 Spore Frog
1 Gnaw to the Bone
2 Doom Blade

I still strongly feel that the deck needs to be GB and remove Blue. I disagree with the brewer there and I am still thinking about whether I have to stick to Sultai for the final deck analysis. Maybe there will be two.

If you have any suggestions for improvements for the deck, please let me know.
