Alternative Creatures - creature replacement.

I would suggest making Destroyers instead of horses, and not devils, because a horse without a rider doesn't look very good. Also, I would suggest making each one available separately, so that everyone can download exactly the creature they want to replace, because not everyone might like completely changing everything. For example, I would personally download Faceless Ones to replace Witches, and I think there are many others who would do the same.
