Face-down creatures flipped by Ixidron are nearly impossible to track

While you're not allowed to look at the opponents' face-down cards, you are supposed to know what they are and be able to track which is which. The current implementation instantaneously replaces the card's object number with an assigned [H#] number.

Either the game log should clearly note which card became which as it flipped down, or it should just allow you to see what they are if they were already face-up.
