I've built a [[tymaret murder king]] edh deck, that wants to kidnap your creatures, and sacc them for value. I have 13 [[threaten]] effects, some repeatable, some for entire board, but most at sorcery speed 3 cmc. I have phyrexian and ashnods altar for mana, 3 or 4 [[village rites]] type effects, and a bunch of [[zulaport cutthroat]] type creatures. Add some regular mana rocks that also sacc to draw, sacc payoffs, and I thought this would be enough, but the deck feels..... Weak and weird. It never gets up and running. The commander is mostly just for flavor (sick name and cool art) and for an early body with (an expensive) sac potential. Have you tried this? What works/doesn't?
#Threaten/sacrifice feels very lackluster

Legendary Creature — Zombie Warrior
, Sacrifice another creature: Tymaret, the Murder King deals 2 damage to target player or planeswalker.
, Sacrifice a creature: Return Tymaret from your graveyard to your hand.
His memories remained in the Underworld, but his cruelty crossed the Rivers with him.
2/2
Sorcery
Untap target creature and gain control of it until end of turn. That creature gains haste until end of turn. (It can attack and 
this turn.)
Goblins' motivational techniques are crude, but effective.

I have three [[footbottom feast]] type effects and I'm removing those because they feel bad. Maybe cut down to one. And it's weak on board wipes, I thought I could get away with advantageous trades. Maybe they need to move in. Spot removal is flavorful like [[bone splinters]] but I might have to add something better and less flavorful. But should I make that compromise? Some decks are cooler than they are strong you know?

It kinda depends on what kind of decks you are up against. Solely relying on threaten is probably not the best, as the value you generate very much depends on the types of creatures you get to steal. This deck seems very good against someone playing stompy dragon/dino tribal or something, but is probably less effective against more spellheavy decks that only run some small value creatures or gowide token .
Perhaps you should demote the threaten theme to more of a subtheme and add more of an own gameplan that can work regardless of what other people are playing.

I build three types of decks:
- good commanders/themes with optimised decks
- good commanders with (not unoptimised, but) deckbuilding/theme constraints
- bad commanders/themes, so let's throw everything we've got at the wall to make the rest work out
Examples: jhoira artifact/eggs/storm - wins turn 4. Tatyova, but a merfolk theme, might win might not, but has drawn a ton of cards and had some fun in the mean time. And lastly, this is a prime example. Rakdos threaten/sac is not a good commander theme. I barely made it work in 1v1, but it can't sustain fighting three opponents. So now I've gotta turn up the heat to make it at least viable.
(And I realised I forgot about solemn simalucrum, it should be a auto include lol)

Rakdos Sacrifice is a pretty potent Pioneer deck, I always think commander players should take some inspiration from competitive constructed decks. Here’s a list that won a Regional Championship: https://www.mtggoldfish.com/deck/5898054#paper
Obviously there are some differences (can’t run Jeggy in a Rakdos commander deck, targeted discard isn’t that good in multiplayer, can’t run 4-ofs), but take a look at what kinds of cards work well. Creatures that want to be sacrificed like Unlucky Witness and Cauldron Familiar are gonna be a big part of your deck

For removal, I think you’re gonna want Edicts that hit each player/each opponent. Classics like [[Innocent Blood]] and [[Fleshbag Marauder]] are great, while newer cards like [[Mire in Misery]], [[Virtus’s Maneuver]], [[Fatal Grudge]], and [[Sheoldred’s Edict]] have some added flexibility

while there's certain things that can be taken from competitive 1v1 decks, it's important to keep in mind that edh is an entirely different format. cat/oven is not nearly as potent in edh as it is in other formats when you can only run 1 copy of each card. you're playing against multiple players at 40 life, rather than 1 person at 20, some things just don't scale that well.

So I haven't seen the suggestion yet but if you want to play a very potent strategy that has a dash of threaten effects that it can abuse, may I recommend
[[Marchesa, The Black Rose]]
It may not be exactly what you're looking for but it's the first thing that comes to mind when threaten effects are brought up in the context of edh.
Sometimes the simplest solution to your problem is the commander may just not be as strong as you'd like it to be. Which is fine! If you prefer staying 2 color and just like Tymaret you can definitely still find improvements. Just thought it should be mentioned.

Yeah I'm spinning into [[ziatora]] right now

Because I remembered that fling was the "fun" part of kidnapping
So a threaten ziatora deck + the big dumb idiots like the yargles and ghalta, and sneak attack!
"But oh what if we did some slimefoot and saprolings too?"
"Oh and the altar/cutthroat/reassembling skeleton infinte combos??"
And suddenly my pile was 200 cards
