I was playtesting Adrieng's version of the deck and I agree with UR Delver matchup. It is favorable, especially the version without Wastelands. Matchup where I do have troubles is Death and Taxes with Spirit of the Labyrinth and Ghost Quarters maindeck. I think I had 1:5 or 1:6 against that deck .. it was abysmal .. so much disruption. Hope people will play good old list with Rishadan Ports. Think about adding 2nd Maze of Ith as you others are testing right now. Any ideas? Although stock version of the deck was much better (~50% or slightly more).
My current sideboard:
3x Ancient Grudge
2x Reclamation Sage (will be 1/1Krosan Grip split)
1x Karakas
1x Bojuka Bog
3x Pyroclasm (don't owe 2nd Deluge and Pyroclasm is better against decks like Goblins, UR delver, Elves)
1x Toxic Deluge
3x Ratchet Bomb
1x Thoughtseize (in my opinion better than 4th Duress)
Still I can't get my hands on Tabernacle which I would play otherwise, probably in the spot of 3rd Pyroclasm.
