Like the few previous posts, I could probably sum up what I have to say about Cresselia using only quotes from this page.
I have to admit, first and foremost, that I did not use Cresselia during the Suspect round as I was to busy working with hail. I have, however, worked before with a rather successful Lunar Dance Cresselia, and I have met many of them in my travels through the land of RU.
As I'm sure anyone who's played enough RU can see, Cresselia, while not contributing much direct offensive pressure itself, stops, while not quite "95%", a fair portion of the metagame. In fact, an unfair portion of it. Also blessed with an array of support moves such as Sunny Day, Thunder Wave and Toxic (but thankfully not Dragon Tail), plus reliable recovery in the form of Moonlight (plus Sunny Day uggghhhhhh), it's an excellent way to wear down the opponent's team, before it uses Lunar Dance, or dies, either way giving your sweeper of choice a free switch-in.
As a wise man once said, "Cresselia is like a banana peel. It sits there, does nothing, and slips up your opponent's sweepers. Except Escavalier, which has no feet."
