This card can be activated when your monster is destroyed during the Battle Phase. Target 1 monster on opponent side of the field ;destroy it, than add 1 monster to your hand with Level equal to the destroyed monster's Level.

Interesting card. 
If I'm getting right, 

A monster is destroyed on your side on field, by battle or effect as long as it's during the battle phase, after which you get a free pickof which monster is destroyed on the opponent's side of the field, and get a free monster of the dsame level in your hand. 

There are decks that would benefit rediculously from this card. The question is; how useful is it. 

First of all; you can't add any monsters if your opponent has only Xyz monsters. 

Secondly; you need to actually have monsters of the same level as the destroyed monster something that doesn't quite speak for itself. 

Thirdly, it must be during the battle phase, thus you're assuming you can activate traps. 

 

All in all; 

This card can be useful in some decks, albeit not all too many of them. Decks out of the top of my head that would benefit of this are... 
Yang-zing (varying from 1 to 4), Monarchs (1 to 6 if you're running fodders and tributes.)

Aliens (1 to 6) 

Dragon Rulers (in tradional format especially) 

 

I'd give this card 6/10, because it has a nice concept, and nice effect, but the actual playing could be a bit hard.
