Has anyone considered trying a Living Wish toolbox? Wish is still active under Teeg unlike GSZ and the card goes right into your hand unlike Enlightened Tutor. It fits into the Sylvan/SDT slot as an additional mode of card selection and is live more often late game IMO. This is what I'm testing:
4 Dark Confidant
4 Deathrite Shaman
3 Stoneforge Mystic
4 Liliana of the Veil
4 Abrupt Decay
3 Lingering Souls
3 Inquisition of Kozilek
3 Swords to Plowshares
3 Living Wish
2 Thoughtseize
2 Cabal Therapy
1 Oblivion Ring
1 Sword of Fire and Ice
1 Umezawa's Jitte
4 Verdant Catacombs
3 Marsh Flats
3 Wasteland
3 Bayou
3 Scrubland
2 Windswept Heath
2 Swamp
1 Plains
1 Forest
2 Toxic Deluge
1 Pithing Needle
1 Oblivion Ring
1 Batterskull
1 Nihil Spellbomb
1 Stoneforge Mystic
1 Ethersworn Canonist
1 Gaddock Teeg
1 Faerie Macabre
1 Phyrexian Revoker
1 Loxodon Smiter
1 Wasteland
1 Karakas
1 Thalia, Guardian of Thraben
I am doing the 3-2 split in favor of IoK over Thoughtseize right now because I think I want to strip cheap enablers more often than I want to strip things with CC4 or more and it saves some life, but that may be incorrect. Also testing not having Batterskull in the main because I have lots of spirits to stick SoFI and Jitte to and I'd rather not be timewalked by Stoneforging for Batterskull into Bolt/STP (or worse, Wasteland-Bolt/STP). In my opinion, if you were ever able to stick a batterskull in most matchups after grabbing it T2, you probably would win just as easily by sticking a SoFI or Jitte while having flexibility in case something distasteful happens. Against tempo decks, I can board it and the 4th SFM in for Thoughtseize. Can also bring it in vs. combo for that extra clock.
I might go to 2 Teeg in the board since it's such a crusher for Miracles and Storm combo, but I don't know what to cut. Teeg is always my first Wish against those decks with Thalia and Revoker/Canonist as backup. Against sneak+show wish for Karakas of course (and board in other combo hatebears over Abrupt Decays). Against reanimator or dredge you can wish for Macabre to buy you time to stick a DRS. (Postboard, do I just want Rest in Peace to win instead of Spellbomb so I can preserve DRS/Souls? I just love drawing that card off spellbomb...)
Loxodon Smiter is because sometimes you just want something huge and it can't be stripped or countered (for example in the late game when attrition has worn both hands down, it narrows the opposition's ability to get rid of it to their hard removal which is really Swords or AD). But I also considered Stirring Wildwood here since it blocks/kills Delver and also can't be stripped or countered. However, I'm a little scared of Wasteland in that case.
