Answer 2

I guess the main purpose is to use it for defense to protect your Gladiators.  I think there are better cards you can use like Shrink, but it could be useful if you have a Morphing Jar in your deck.

Answer 3

When version two came out in Korea, it was a trap/magic card intended to be used with a monster.  However, that monster does not exist in America.  Therefore, it is useless.
