Is Illusion just some kind of taboo subject? It caries probably the most risk out of any ability in the game. You are essentially not only bluffing an item, difficult to do already, but bluffing an entirely different pokemon. This ability was one of the main reasons I liked this concept. Unburden is another great idea. Basically, you trade an item for a powerful ability. Sure, you get a free salac boost, but at the cost of no item. How can you play around this? It would be very interesting.
