That would be me :wink: I used a full set of Sculler because I didn't have Bobs at the time, and I was also using 3x Thoughtseize/2x Iok/2x Liliana/3x Hymn all in the maindeck. I didn't realize it, but the meta-game I was diving into was swarming with combo. I took first in my first tournament there because of the insane hand disruption. I was also playing a full 3x Sylvan Library because I didn't have Bobs. I needed the bodies for pressure because believe it or not Bob does make a difference in combat, especially if he is feeding you discard/removal to keep the game state in your favor.
Fast forward a month and I've got my set of Bobs sleaved up, but I end up dropping the Hymns for Scullers. I found that Hymn is only good in narrow cases, mostly against decks like RUG Delver and Burn. Sculler had always performed amazing for me, so I had no reason to cut in that department. Curve Thoughtseize>>>Sculler>>>Liliana and live the dream, baby.
In regards to Dark Tutelage, it's just plain wrong. If you have access to :b::b: then you are much better suited to using Phyrexian Arena instead. I think both options are wrong if you have access to more Sylvan Library's. I tried Arenas for a little while, but it got incredibly awkward. A time walk on turn 3 with underperforming value was really lousy. Sylvan Library at least gives you the equivalent of a Top activation and the option to draw into more gas. I'd rather draw one card that is the best of my top 3 than get an extra card that might not even matter. With Bob, you're getting the body and a significant threat if left unanswered. Whenever I've resolved a Sylvan Library it hs been the stone cold nuts. Play 3-4 of those before you try something like Dark Tutelage or even Phyrexian Arena. It curves out better and only hurts you mildly more than Dark Confidant. The important part is that it feeds you insane card quality as long as you play at least 7-8 fetchlands and a few other shuffle effects (GSZ, Knight.) If you rock some sort of lifegain in the maindeck, like if you're doing SFM + Batterskull/Jitte, then Library gets even better. Padding your life to allow for extra cards is pretty sweet.
My current quandry is my lack of Goyfs...I have 2 now, but I think getting up to 3 would be ideal.

4x Deathrite Shaman
4x Dark Confidant

(maindeck = 61 cards. I'm playing 22 lands with 61 in the main...it feels a little low, even with Deathrites and GSZ. I might have to drop to 1x GSZ to make room for land #23. Testing will tell.)
Sideboard:
4x Natural Order
1x Progenitus
1x Empyrial Archangel
1x Enlightened Tutor
1x Pithing Needle
1x Ethersworn Canonist
