Ok, I know that this is a bit stupid but, technically, you could play The Raven Quill, attach it to Astronomical Atlas... and later be able to commit que Quill to an skill test through the Atlas's ability ¿right? same with any card you attach to the Atlas by any means?
It is stupid because it is super-inefficient but, is it valid? additionally, there's no customizable ability in TRQ other than spectral binding applicable to the Atlas. Maybe supernatural record to fetch for another Atlas? If you use that one, you could fetch for a first Atlas and play it with TRQ attached to it, then commit TRQ to a test to have it back to your hand, then play it again to fetch for a second Atlas, commit it again (12 resources by now xDD) and play it to fetch for a second tome/spell you have writeen down in Endless Inkwell.
Just put 3 Astounding revelation to trigger for 6 resources during those fetchs... so the total cost would be 6+3+(third tome/spell cost).
Even better, what if you come across TRQ when using the Atlas's ability? it attaches to the Atlas and applies all its properties right away.. without playing it and paying its cost, costless and actionless
