Wincons for B3 Dimir decks like Emett-Selch of the third seat?

I've been trying to get out of my comfort zone. A while back I asked a similar question for Izzet with Stella lee and got some good responses so I'm trying this once again.

It doesn't have to be for Emett-selch specifically, though I like both of his cards. I've just noticed a lot of comments and videos where people seem to struggle with how to close with this kind of deck and I tend to agree.
