Forum:Blackwing-sirocco

I was playing the new yugioh championship 2010 ds game and saw Blackwing-Sirocco the Dawn's effect activate and transfer his attack and other black wing monsters atk to a selected blackwing target. After the end phase the added atk vanished from the monster so that made me curious. Does the added atk disappear after the end phase or is it permanent? DeVast 12:20, March 18, 2010 (UTC)
