Cresselia

Cresselia's amazing defenses and ability Levitate allow it to wall some of the most powerful attackers in the game, such as Salamence, Rayquaza, Groudon, Garchomp, Palkia, Giratina-O, Arceus-Ground, Terrakion, and more. A decent support movepool allows it to support the team through methods such as Thunder Wave, Toxic, Safeguard, dual screens, or even Trick Room. Cresselia lacks a Rock- or Electric-type weakness, meaning it takes neutral damage from Stealth Rock, Stone Edge, Bolt Strike, and Thunder, while sporting roughly the same physical durability as Lugia.

Cresselia's main flaws are its inability to phaze like Lugia, laughable offensive stats (especially by Uber standards), and vulnerability to Toxic. Cresselia's weaknesses to Dark- and Ghost-types also hamper its tanking ability. Lugia overshadows Cresselia for the most part, due to the latter's limited movepool, overall inferior stats, and the need for sun support in order to have reliable recovery in the form of Moonlight. The inability to counter Extreme Killer Arceus also hampers Cresselia's usability as a physical wall.
