Latias

Despite competition with Latios, Latias still makes for a great Pokemon in the metagame thanks to its superior bulk and access to Healing Wish while still offering the qualities that Latios brings to teams, such as sharing its same typing, Speed, and most importantly, an immunity to Spikes and Ground-type attacks thanks to Levitate. These excellent traits are key to keep checking threats throughout a game like Breloom, Terrakion, and Keldeo. Latias's superior bulk also allows it to act as one of the best checks to special attacking threats such as Thundurus-T and Keldeo, making it a very good answer to rain teams. Its Speed tier is incredible, as it's the defining benchmark of the tier and allows Latias to outspeed threats such as Terrakion, Keldeo, Garchomp, and Thundurus-T, as well as Speed tying Latios. Latias's main flaws are having stringent competition with Latios due to Latias's comparative lack of power to Latios and Tyranitar being very common and consistently Pursuit trapping, which is made even easier by the aforementioned lower power.
