Help creating a Dimir card draw deck

Hi there, I'm pretty new in MTG Arena and trying to build a blue/black deck centered around bouncing and card drawing.

Playing standard, since I think that's the default. Currently playing around with something like this, based on the cards I have in my collection and the small amount of wildcards I have left. I don't know what to cut or what essentials I might miss. What is a good place to learn more about deck building?

Lands need to be changed to include duals of course. Sideboard contains some other cards I thought about but think are not as well suited as what's already in there. https://aetherhub.com/Deck/dimir-draw-idea
