Yea and I know one of the rules allow a player to change decks between rounds but like who's really going to want to change their entire deck just to accommodate one card.

To be fair though Matt the idea is really really cool in theory. I mean it got me thinking what if when you do this the Buddy Monster you stole would change into a brand new card. Much like if the Buddy is Drum Bunker Dragon and you are playing Magic World the monster would change into it's Magic World form. But sadly not every monster can do that :P
