Select 1 monster on your side of the field to activate this card. While you have 2 or more monsters on your side of the field, and all monsters on your side of the field are in Defense Position, the selected monster gains 700 DEF. When the selected monster is removed from the field, destroy this card.
You might be able to use it with Canyon. There certainly was one of the stage challenges which was to win on opponent's turns 10 times with Jaden, I think. I know I used Canyon and big Rock things then so maybe it would be good there.
