Very interesting, and I have a question or two about it. I would assume the switching part means the former Inuyasha would go to your hand, otherwise it would be discarded due to the unique rule, but if so this Inuyasha would not need the effect of discarding cards on the former Inuyasha. But I would think that if it was returned it would discard them anyway. Sigh. Anyway, if you can use this right, this could be a real pain to your opponent, since this would completely take away one opponent`s character, by removing it from the game, regardless if the attacked character had higher colors or not. However, this will take skill to use well, since it should really only be used when you really need to.

Casual:3/5
Tournament:3.5/5(Must be in an Inuyasha heavy deck with Inuyashas that share most colors)
Art:2/5meh. I`m not impressed.
