Some great entries so far. Another example card from me, just because they're fun to make.
One of the scariest things black can do on its creatures is make them recurring threats. If your opponent can't do anything about them, they'll quickly take over the game.
I'm going to keep doing examples, which is really a sneaky way of bumping the competition up to the top of the conversation.
What's scary? Ancestral recall. One mana for three cards? That's just terrifying. This doesn't have quite the same raw power, but it should still be pretty intimidating when you cast it.
Here's a card. I created it about a week ago, but didn't think it would work well in this contest. The fact that this is an instant makes it twice as scary. https://mtgcardsmith.com/view/carrion-feast
Cool. I already used up my max amount of entries permitted, but that is good information for people who want to make transforming cards. Thanks @TenebrisNemo and @Undead
@TenebrisNemo your card Forbidden Art would be cool for my Sagara block! The main villain of the set, Skullbrander, he can transform creatures into black Skeletons (in addition to their other colors and types) it's how he built his Skeleton Pirate crew.
My final example card, released as we enter the last eight days of the competition. Nothing screams dark power than draining your opponents life total.

I don't know if this is really simple enough, so I'll come back with more.
