Does it remain a ghostrider when no longer threatened or does it lose ghostrider powers when no longer threatened? I think the latter is better way in my opinion.
It can result in all sorts of strange things, you can make your knight threatened by a pinned piece, especially if you make a discovered attack on your own knight you can put opponent in check in this way, and even get out of check by interposing the threat to the knight.
