I like what you got going on here a lot, and as such I can only offer some slight edits. Baleful strix and cloud of faeries are 100% better than any card that scrys or is unblockable. With that being said, Artificer's Assitant and Quickling are the weakest of your creatures, these two are easy switches. Quickling as we talked about actually doesn't synergize with your deck as much as it seems. Your alternate costs are much better, and I like what your doing with the splashy spells. With that being said, you are top heavy on splashy spells, I would cut at least beacon of tomorrows and karn's temporal sundering, as tapping out pre combat is bad for you. There is a black commander miracle spell, you want that in this deck, as well as the other weaker blue miracle cards. These are likely better that big spells you can't cast easily. I also think undaunted is a little weak, and although delve is te right idea, you don't actually fill your graveyard that much, so they actually look to be full retail for you most of the time. Instead, that rags //riches definitely comes in, as does discovery// dispersal, commit//memory, the mono black one that kills creatures or exiles, and decree of pain. Similarly desertion and snuff out are excellent compared to things like curse of the cabal and dead drop. I think dream halls is ok with some splashy cards and tutoring, omniscence is better than a time walk. You don't want to be all in on that angle, just have it be something you assemble. I think Omniscence/Enter the infinite is the late game combo you want. Abjure is absurd, I didn't know about that card. Now I do! It's under a 1$ I think I'll buy them all. Also, take another dive into cycling spells, especially boon of the wish giver and street wraith. Cheap cantrips with big CMC's are excellent and pair well with all the scrying you can do. You can set up miracle at instant speed that way. I like scheming symetery as also an ally maker for this reason.

Lastly, who you playing around with? Get that sol ring in their son! It is never ok to cut it!
