Not really; while Groudon was the most common partner in 2010, Rhyperior, Snorlax, the aforementioned Krookodile, Mamoswine, and Marowak are all also good partners for Cresselia, and all are quite similar to Groudon of 2010, intended to abuse powerful spread attacks. However, I don't really see a huge difference between the Trick Room set already in the OP and the standard gec posted except for Psychic over Ice Beam and Light Screen over Reflect. Sitrus Berry, like gec posted, is definitely a viable option to allows Cresselia to take very powerful hits (think rain-boosted Hydro Pumps) more easily.

I see Psychic as a stronger option than Ice Beam, because it hits Pokemon such as Hitmontop that normally stop Cress's partners for super effective damage, while I don't see how Ice beam attains significant coverage outside of Garchomp.
