Raichu

Raichu may not be the best Pokemon in the VGC metagame, but it's still a Pokemon to consider. This generation, Raichu received a new addition to its arsenal from the Dream World: Lightning Rod. This ability grants Raichu an immunity to Electric-type moves, as well as a Special Attack boost when hit by them. Additionally, Raichu still has the tools it has always had: a wide movepool, excellent Speed, and good Special Attack. Lightning Rod makes Raichu an excellent choice to use on any rain team, as it can draw away all Electric-type attacks aimed at its Water-type teammates and obtain the aforementioned Special Attack boost. However, Raichu's terrible defenses allow most powerful neutral attacks to strike it down. If it weren't for Lightning Rod and Encore, Raichu would be outclassed by other Electric-types such as Zapdos. All in all, Raichu can serve as a useful counter to rain teams, an option to use on your own rain teams, as well as a powerful special attacker on an offensive team.
