...yeah I'm just going to scoop

So what's the goal of the deck? It seems to be exploring a bunch of different paths but not really doing anything too spooky on any front. Your curve tells me you're not aiming to go super-late, but you also don't have enough threats to rush a midrange deck imo.

Specifics:
- I think you need at least 25 or 26 lands; your deck has a lot of mana sinks and I'm assuming you want to consistently drop Reaper on turn 4. Courser should be considered as well!
- Maindecking Reclamation Sage, Return to Earth, and (maybe) Erebos is probably a mistake, those cards are 100% board. Heir of the Wilds perhaps?
- On that same note, Ferocious seems like a very relevant keyword for this deck, given that there are 6 four toughness creatures and you can make Rakshasa Deathdealer a 4/4 easily.
- Consider adding blue for Sultai. Having a graveyard deck without Sidisi just seems like a mistake, and the charm gives you great options for what the deck wants to do. You can access the delve draw spells, which will let you get rid of lands and undesirables so that it's easier to hit with Tasigur.
- Consider Abzan as well. There's a lot of self-harm in this deck and not a lot of ways to gain life other than the two god artifacts, siege rhino solves that problem easily, especially since whip is involved. Maybe up the Whip count to 2 or 3?
- I definitely have looked twice at Sudden Reclamation, I'd normally consider Satyr Wayfinder to be the best graveyard filler because he also provides a body, but I haven't played enough Sudden Reclamation to know for sure.

I'd narrow down the scope of the deck a bit, as it stands now it looks okay but it's gonna have a bad time against focused decks.

Looking forward to seeing where it goes!

That's a pretty neat version of UB Control! IRL, you're probably going to be going to time a LOT, especially given your win-con pre-board is just decking them or Ashioking them. Some thoughts:

- I definitely love the Monestary Siege; I was considering how I could fit that in my list. My only holdup was that the 3-slot is so crowded in that deck already and often you need to cast removal or leave up counter-magic on that turn instead so that you don't die pre-board-wipe.

- While this deck is slow and needs access to all its mana, 12 tapped lands is a lot. We need to hit our land drop nearly every turn up to 5, and if you draw a tapped land on turn 5, it's gonna hurt. I'd suggest replacing the Opulent Palaces maybe a few fetches for just the island or swamp - they even give you more fodder for Dig Through Time! Also, since we do need to hit our lands, running more is something you may want to consider.

- Instead of Dissipate and Nullify, I like either 2 Negates (to get into counter-wars or take out walkers (since 2 mana is easier to keep up than Dissolve), or if you want to stay conditional with a strong chance of big payoffs, 2 Disdainful Stroke. I'm considering maining that over the Negates, with the Negates being an option post-board vs control/Jeskai.

- I was going to say that Cranial Archive makes more sense post-board, but then I realized Ashiok/decking is your win-con :P. If you're hoping for the game to go that long, I'd consider more sources of lifegain, such as a 3rd Radiant Fountain, as UB Control suffers pretty badly without it, and if the game goes forever, an opponent might just be able to get enough burn that you can't counter ALL of it.

Looking forward to playing mirror match!

I read STDs instead of standard, which looked hilarious given the deck name.

While you DO have some big butts, I'd like to see some protection against Supreme Verdict in that deck, given what a stable of Standard it is (and sadly protection won't save you). Maybe Rootborn Defenses or the Ajani's Presence? Rootborn has the tiny bonus of giving you extra tokens if you have Heliod in play, and Presence triggers heroic.

I might consider cutting the 2 Yoked Oxs, since Trailblazer is a straight upgrade (6 is a lot of 1-drops), the 2 Oppressive Rays (cause it just seems bad), and maybe Path of Bravery (maybe?). On addition side, I'd go 4-of on Banishing Light, since you seem to be pretty light (PUNS) on removal. I'd also add another Heliod and his Spear, since you definitely want Heliod in play every game.

Several ways you could go:

1) 4-of Eidolon of Rhetoric, and then just find more creatures/enchantments with activated abilities so you stay under the 1-spell per turn limit (and can save mana for Brave the Elements or Rootborn/Presence)
2) Since you have so many enchantments, and Heliod gives you even more enchantments, Sphere of Safety?
3) Not sure what white has in Nyx, but something fun with Constellation?

Fun deck overall - keep me posted on future iterations of it!

My one final thought was about using Master of Cruelties as one of your demons, but you'd have to splash a little red in there (or hope you don't draw it).

I think Immortal Servitude is what really makes Shadowborn Apostle work, otherwise SA is simply a terrible card. My only other concern is that you actually get enough apostles (out of 13) into play to summon a demon, although grisly salvage will help with that.
