I created this deck after playing against a Kaervek the Merciless deck in my playgroup that was particularly oppressive. What I'm looking for here is a deck that hurts everyone else except for me (within reason) by sacrifice, loss of life, or damage. There's a small chaos element to speed up the game as well. I also included a small 1 CMC artifact package to synergize with Salvaging Station. Definitely not a big engine but some worthwhile interactions if I'm able to pop Wayfarer's Bauble a few times
What major disruption cards in BR am I missing from this list?
You can't play Temporal Trespass with Tsabo Tavoc as your commander. And to piggyback off of that, it seems that you are lacking in the draw department. I count 6 ways to draw (not including Temporal Trespass) 7 if you want to include Decree of Pain. I am unsure what your budget is, but there are much better draw spells you can fit in for relatively cheap $$. To name a couple, Night's Whisper, Faithless Looting and Ambition's Cost. You need much more drawing power if you want to be able to keep the pressure on people and them not be able to play through it. I would also recommend lowering you CMC.
Also, how often are you taking advantage of Waste Not? Are you looking to get advantage from it or is it a nice to have? At the moment you have 2 cards that can make people discard. You can kill 2 birds with 1 stone here. Adding more cards like Dark Deal, Wheel of Fortune and Dragon Mage will give you draw as well as forcing people to discard.
Lastly, I think you need to figure out what exactly you want to be doing with this deck and streamline it. There seems to be multiple things going on..which is fine, but what you do with the deck, you want to do it well..not just okay. Anarchist jumps out as something that doesnt fit, Zealous Conscripts as well.
You could make a spot for him, but playtesting him in my Mono Black Control/Stax has shown him to be too slow and underwhelming. Give him a try, maybe he will work better for you.

Good suggestion. I included it due to its equip to legendaries for free and a lot of the other creatures I run are legendary.
Is there a spot in this list for Ob Nixilis, Unshackled in your opinion?
