Nice, Soulherder seems like a fun deck to play, I have enjoyed the Soulherder streams I've watched. I'm not familiar with the deck other than watching streams, it seems it can be a bit hard to play right, although I understand the points, so I don't got any pointers on MB, probably best to ask in a dedicated Soulherder thread (this thread seems to be dead anyways, and probably will be until next batch of eldrazi :p).
Sideboard seems a bit off if it's not built to respond to your playgroup where most play burn and affinity. Would probably add a couple of more counter spells. You already have Knight of Autumn in MB, so 4 Thrag seems a bit much. I would also add some removal both in MB and SB, Engineered Explosives/Winds of Abandon(as a budget, works well with soulherder) and/or Path to Exile. And I would add some graveyard hate even tho Hogaak is gone.
I've been goldfishing with Once upon a time, I believe that to be an upgrade and to further improve turn 2 Thought-Knot Seer by being able to dig 5 for either him, a dork or a Temple.
Stoneforge-package could probably also fit in here, as it seems to be crammed in every white deck these days.

I'm still having a lot of fun with the deck!

Could Eladamri's Call work? With it we could play a couple of 1-off creatures like Tireless Tracker, Shalai, Voice of Plenty or something spicy.
