Hey deadmedix, moving forward I plan to change very little about the deck. I outlined my changes to the sideboard on both r/spikes and r/modernmagic, and have decided that I'll be trying a Declaration in Stone over the Main Dismember and a Blessed Alliance in the side.
So Leyline is certainly a more powerful card, but far less flexible, Relic has alot more play to it than it looks. Relic does a better job enabling processing because it can be drawn later and for a measly mana or 2 give you all the exile you need. Draw a card is also a rider I need on my otherwise dead in certain matchups maindeck card. Leyline is a consideration in the side for a heavy Dredge meta, but after talking to Ross Merriam it seems our matchup is already fine with the Relics. Most other cards in the sideboard have broad cross archetype application, Leyline is just too narrow to bring in often and thus not worth the space. I actually had 3 in my board the night before the Invi and cut them for 2 Surgicals and something for other matchups. I've since cut the 2 Surgicals for a single Rest in Peace, thus freeing up one more slot which I really really like. And you should never play a card to pitch to something like Brutality, it simply makes the downside of having it stuck in your hand mitigated a small percentage of the time. It may feel worse, but you can pitch a Relic and you're in no worse spot.
Scullers feel great at 3, I usually want one but the second has such diminishing marginal utility. However, a bear is a bear, so drawing 2 is fine. I could cast them on time usually, and if I couldn't its because I had Ghost Quarter or Eldrazi Temple, which naturally put me on a game plan where I don't necessarily need to cast an early Sculler, IE a fast Strangler and TKS on turns 2 and 3. And Ghost Quarter is really like a quarter of a colored source, its surprisingly common to Ghost Quarter yourself to cast colored spells. Usually I do that on turn 3 so that I can play another 3 mana worth of stuff the following turn, but sometimes turn 2 could be necessary.
The deck is very controlling but I don't like Bitterblossom for a few reasons, its very slow and we don't have Goyf's or Mistbinds or anything to synergise. The other is Lingering Souls is just a better card by a country mile, and between it and Blight Herder we have enough 1/1s running around. Whispers of Emrakul is a trap card, Hymn is rarely good past turn 2, and delirium is unattainable before 2. I play Legacy Jund and have a love/hate relationship with Hymn as is, making it worse certainly makes me ok with not ever playing it
Hey hankeypank, I have to recommend a complete overhaul of your board. What you need is cards that address specific matchups in the meta now, for example Flaying Tendrils and Disenchant are both terrible in the format. As you can see from the below link, I come into nearly every matchup not just with cards to bring in, but roughly the same number of cards I want cut. I build my sb in an excelsheet very scientifically, and make sure every configuration of my deck has a good curve too
Hey Darth Bunny, I'm the guy. So Zealous Persecution was a mistake on SCG, the card is so underrated. I even bring it in against things like tron sometimes just for the anthem, it can increase your clock by a turn in a pinch. The brutality was great all day, I want another in the 75 perhaps. Brutality is so flexible, and the tempo advantage you get by turning cards into effects is great. Infect and Burn are the matchups where its A+, and only against tron is it embarrassing. The lili is awesome, I've played up to 3 in the deck and 1 feels right, you never want to draw multiple.
