Latias

With the release of Soul Dew in ORAS, an item that boosts Latias's Special Attack and Special Defense by 50%, she returns to the forefront of the Ubers tier with both new and old tricks. One of the newer ones is her access to Defog, which provides a team with an excellent non-Arceus Defogger and allows her to function as an effective defensive pivot. Levitate is as useful as ever due to the common use of Ground-type attacks, and further helps to mitigate entry hazard damage. Latias is also quite useful both defensively and offensively, thanks to a great base 110 Speed, strong offenses and defenses, and an ability to check both Primal Groudon and Primal Kyogre. She is not without flaws, however; although Pursuit has limited distribution it is still a very dangerous threat. Latias is also hard pressed for free moveslots and needs defensive investment to do her job well, meaning her damage can be lacking at times. Certain Fairy-types can also pose a significant threat, along with common Dark-types such as Darkrai and Yveltal. Latias is also in competition with Latios to an extent, although her comparatively higher bulk gives her a niche even for offensive sets. Another niche she has over her twin is the move Healing Wish, which is an incredibly useful move for offensive teams.
