Thought of this during ME 351. Turns out someone else thought of it as well (see decks including Search the City). Pillaged the idea of using Sphinx of the Chimes, which is a fairly obvious include here.

Should narrow down which Demons, considering which ones you will actually want to tutor.

Works alright on paper, but I think practically it will be weak, simply due to its propensity to draw into the cards it wants to tutor, and because the CMC 2-3 part of its curve is lacking. Needs a bit more oomph.
