Que quagsire es check de latios es el fail mas grande que he visto en este post.
Draco Meteor Specs no lo aguanta ni de broma, aunque sea max sdef (los hay?), y aunque aguante 1, el segundo es tambien a maxima potencia por culpa de ignorante (ahora jode en vez de ayudar xD) y cae fijo.
Y Latios CM lleva siempre psyshock para special walls, asi que le da igual que defensa haya maximizado quagsire, le da KO por un lado o por el otro xDD
Checks y Counters para gen 5, segun smogon (ya han metido en la web la mayoria de pokemon de 5ª gen)
Checks and Counters
Although most of Latios's checks and counters depend on the set you're using, a couple of Pokemon can be called 'universal' checks to the dragon. Most offensive sets are easily taken care of by Scizor, Tyranitar, and Blissey, as the former two can trap and KO Latios while taking minimal damage from his attacks, while the latter can simply sponge Latios's attacks and slowly stall him out; however, it should be noted that all three of the aforementioned can be bypassed if Latios carries the appropriate move. In addition to Scizor, Tyranitar, and Blissey, almost all defensive Steel-types, such as Skarmory and Jirachi, and specially defensive walls, including Chansey, perform as excellent checks to Latios, as they can sponge the majority of his attacks and slowly wear him down. Lastly, Latios will fall to almost anything that outpaces him; prime examples of such Pokemon include Thundurus, Starmie, and Deoxys-S, which are all able to KO Latios with the appropriate move after some residual damage.
