Rather than gatekeeping a thing that, in the Realms, is effectively the lowest rung of divination available to most people (a type of item magic) - could we just rewind to about 2014 and let people use items with div focus to get both auras and access to the deck?
I also think the Loremaster Gift of Scrying should just do that as well because its weird you can scry... but not anything else? You can jump the que from lower magic but have the ability to farsee. Okay, whatever then.
I have a few suggestions that keep it grounded to recent changes but with respect to the past:
I. Loremaster - Gift of Scrying should literally just do all of those things passively.
II. If you have lesser focus from any source + have ranks in the UMD skill you can use the Deck of Stars.
III. Greater focus obviously works as intended.
That's it.
