Cresselia

Cresselia is one of the most prominent defensive Pokemon in Battle Spot Singles. With defenses on par with those of Ubers and an excellent defensive ability in Levitate, Cresselia is capable of checking some of Battle Spot Singles's biggest threats, such as Mega Kangaskhan, Garchomp, Landorus-T, and Mega Salamence! Additionally, Cresselia has an excellent support movepool to take advantage of her bulk, with game-changing moves such as Lunar Dance, Thunder Wave, and Trick Room, and access to a recovery move in Moonlight. Few Pokemon in Battle Spot Singles can come close to Cresselia's combination of support and checking power!

Sadly, Cresselia's wonderful defensive qualities are hampered by her mediocre Psychic typing. The only particularly useful resistance she has is Fighting, while her typing leaves her vulnerable to deadly special attackers such as Mega Gengar, Aegislash, Greninja, and Hydreigon and even hinders her against some physical threats such as Tyranitar and Scizor. Furthermore, Cresselia's poor offenses mean that these threats can usually come in with very few issues and that Cresselia is often setup bait.
