The cards are being exiled face down successfully, but (on android) I've been unable to find any way to play them.
As an aside, it also seems weird that they show up face-down for me? It seems like an unnecessary added complication, maybe have them show as face-up for the player who is able to look at them anyway. /Shrug.

I should also add, I've tried this both with performance mode enabled and disabled, and both ways the card isn't castable.

Is there a button to see exiled cards? I recall for a similar card they showed up there.
