No it aint. No one disputes Fey Touched would be good even without the 1st level spell, but even if you only have one encounter per day an ability that lets you maybe avoid just one attack is garbage, and if you save it for when an enemy makes a saving throw against a team mate's critical spell you will see lots of days go by when it isn't used at all.

Silvery Barbs is only good if you can spam it, or have suck-or-save spells you want to boost.

It's extra-bad for rogues, when it's competing with Uncanny Dodge for your reaction.
