I'd use my lovely Milotic, Venus, for Beauty - Open up with Rain Dance, follow with Surf, then use Iron Tail, showing the glistening metallic surface of her fin covered in water droplets. To finish off, she'd build a slide beneath her with Ice Beam and slip into my arms for a graceful finish.
Sly, my Swellow, would use cool moves, such as allowing the light of a Hyper Beam to play on her Steel Wing Attack.
...Can you tell that I like shiny things?
