seems like you aren't really taking advantage of jQuery. I don't speak mooTools, so I may not get this completely right, but I would try something like this:
jQuery(document).ready( function() {
//you could convert this to jQuery too, of course
mySlide = new Fx.Slide('advert');
mySlide.hide();
} );
jQuery(this).wrap( '' )
.parent('.overflow-wrapper').css('overflow', '' );
