When are we likely to get Hour of Devastation added to the card database? And Commander 2017, for that matter.
I have Hour on mine. Is your ISO up to date? And there was something about older devises on here that you'd have to find.
I see you figured it out already, but here's the story for others: http://imtgapp.com/forum/index.php?board=8.0
Not sure if this has been noticed yet, but a couple of cards are missing from the Commander 2017 update.
Bloodsworn Steward, and Crimson Honor Guard, from the vampire deck. There may be others, but I'm not sure yet.
EDIT: Just checked, and it seems the legendaries out of the Vampire deck are missing too.
We fixed these with update 223, thanks for the heads up!
