Unfortunately not, it was recently errata'd to change them to face-down Defence. (The OCG's starting to crack down on cards with weird, possibly unintended mechanics.)
Interestingly the picture of it in the official webpage for the set uses the pre-errata wording. But it probably still changes monsters to face-down Defence in Duel Links anyway.
.....huh, that's weird. Then we might going to get the pre-errata version after all.
I decided to check the card's release, and I found out that despite the official errata, there is NO official physical reprint yet that has the errata, meaning, in a sense, the errata is not yet fully official. Perhaps they are still reconsidering the decision to errata this card's unique effect?
That's untrue. Any official errata is in effect the moment the errata happens, you don't need a physical copy to exist. If you went to a tournament IRL today and played Darkness Approaches, it would flip a monster to face-down defence. (Assuming the judge knew what they were doing.)
