If you're looking for a quick and easy fix on a large deck that has 16 pixels of unwanted empty space above every card, you could use The Listener to fill the rectangle of every card covered by the menu with solid black like so:
each c in deck.cards c.image.paste[image[c.size[0],16].map[0 dict 1]] end
The Listener is a very powerful tool for doing things that would otherwise be extremely tedious and repetitive.
I strongly recommend experimenting with this sort of thing in a backup copy of your deck to ensure you don't accidentally lose work!
