Not sure if it's addressed in the PTS version, but at least two cards on live have naming errors:
Currently, one of the card's called "Slight of Hand":
Which is a(n apparently common) mistake in spelling the phrase "sleight of hand". Card's art is correctly named as "Sleight of Hand" in the files, so at some point
someone got it right.
The other card in question is "Shadow's Slumber":
The art file for it is named "Spellbound Slumber", which is more appropriate, considering that we see a Khajiit casting a sleep spell on a guard, rather than a shadow slumbering or a shadow putting the guard to sleep. One might try to argue (for whatever the reason) that the Khajiit in question moves like a shadow, therefore the name still works. However, we have seen the so-called shadow in Jeering/Prowling/Stubborn Shadow cards' art, where it's clearly just a shadow of a Khajiit, rather than one in flesh and blood as seen is "
Shadow's Spellbound Slumber".
