Some thoughts:
All the best 2-drops: So I wanted to try playing a build with pretty much all the best 2 drops in MTG. Batterskull is a huge pain for Jund to deal with and Tarmogoyf helps keep you alive against fast aggressive decks. Bob, of course, is amazing against the control decks.
Top over Sylvan Library: I've always been a huge fan of Sylvan Library, but in today's meta with all the Abrupt Decay's all over the place, I wanted my card filtering spell to be protected from AD. I'd love to be able to fit a 3rd Top in there somewhere.
Lingering Souls over KoTR: As much as I love the flexibility that Knight gives us, I think Lingering Souls is too strong right now, especially against Jund and control decks. Having SFM + Cabal Therapy really makes Lingering Souls more powerful than in any other deck.
This build is considerably weaker than the KoTR builds against the Show & Tell decks, which I tried to shore up with a little more targeted discard in the main combined with the faster eTutor board packing O-Rings, Pithing Needle, and Nevermore. I've always loved the flexibility of the eTutor board, so I went back to playing it.
Sculler was also something I wanted to try in the sideboard as a pseudo hate bear since I can't consistently get Teeg out due to no GSZ.
The build has been playing pretty well in testing so far though so I thought I'd post it up here to give people some more ideas in a slightly different direction to go.
