Cress descending down to the RU tier was a godsend to the tier. She alone increases the diversity of this metagame, reviving the playstyles of stall and manual sun.
Cresselia is a very reliable wall in this meta. I've run the T-Wave+CM set and it's quite effective. And powerful too. She is a great wall to say the very least, and her presence makes stall powerful. Is it broken as a wall? No, not at all. Both Escavalier and Absol make solid counters to the set, Esca smashes Cress with Megahorn, while Absol hits with an SD boosted Night Slash. Drapion is also decent thanks to SD and Taunt, but Drapion sucks anyways, so that's not a big deal. She makes the meta more diverse, rather than full offense, we can see the light of stall too.
Cresselia is also a great summoner of weather, particularly sun. She is a very durable Pokemon that can also take advantage of sun with a boosted Moonlight, and thus can set up the sun many times. This really helps with Charizard, Lilligant, and Sawsbuck, and makes Sun teams all the more dangerous. Cryo can use SolarBeam, and also spin for the team. Plus, Lunar Dance is great for healing 'Zard when he's worn down. I think Cress can make Sun viable again (Though, only sun.)
Nonetheless, do I say Cress is broken? No, not at all. She is countered easily by threats such as Escavalier, Absol, and Crawdaunt. Does she have a negative impact on this meta? No, not really. She actually makes the metagame more diverse by changing it from sheer offensive to allowing viability of underrated playstyles such as Stall and Manual Sun. So in conclusion,
I, for one, say bring Cresselia back into RU.
