The problem is this card cannot work on its own. Switching your opponent's monster to defense position is like child's play and you are still going to lose after your next turn. I wish that Change of Heart/Snatch Steal is here instead of this.
You are trolls? Correct? If there is a spell in this game that can easily turn a table is this one. If you believe Snatch Steal and Change of Heart are healthy cards for the game you gotta have a problem.
The majority of people dont know how to properly use this card. This card can easily switch tables or end a duel out of nowhere. However most people just use it as a defense mechanisme.
