Invoke duplicity is on occasion really good IMO. It's not universally useful, but at times it's been a great boon. I've had the occasional use of Dimension Door too, but not frequently I'll admit. The domain spells are of varying quality.
I respecced her to Light after a certain story evolution took place. The spell picks are nicer but concentration already limits how many spells you'll be using and having one additional nice option isn't as game-changing as you might think. Invoke duplicity is offensive and warding light is defensive, and IMO offense > defense.
Trickery isn't half as bad as some people make it out to be. My only wish would be that the first level domain spells contained at least one with more combat application, such as Faery Fire, Tasha's Hideous Laughter or Color Spray.
