Awesome!
I'm trying to think of other slogans.
Bricks: The only attack
Don't punch 'em, Brick 'em
Bricks: Building a path to your face
Maybe a pick of her pitching it, like a baseball bowler or something and the close image of the brick flying through the air.
CATCH: with your face.
Maybe think about embossing the word "BRICK" onto it, or indenting it. I always liked when the bricks were labelled in the sketch comics, it just drew a laugh out of me.
