Now, my question is, is this normal? Has it happened before?
Like I said, I have a Captain of Gondor (foil) that looks like that and traded a second copy that looks like that.
As to the question regarding whether or not foils have been misaligned before, yes. Most of them ended up in Reflections packs where Decipher threw in all of the extra cards that didn't pass quality checks (hence, mis-cut cards, misaligned foils, etc.)
