I don’t think the answer quite means what you’re thinking.
If MaRo’s answer had been no, that would mean the only way to access these mechanically unique (and tournament legal) cards would be in the limited print run secret lair. That SEVERELY restricts supply, which would cause any cards that are needed for tournaments to spike to hundreds or thousands of dollars, depending on the format.
@Ithorian @mike I agree that they shouldn’t be standard/modern legal in the first place, but further restricting the supply would only make situations worse
