Raichu

Raichu is probably one of the best Fake Out users in the game. Raichu was one of those lucky ones that got a boost to one of their stats in XY, and for Raichu, it was given to Speed. Its new base 110 Speed allows it to outspeed most of the common Pokemon in the base 100 Speed tier and provides it with one of the fastest unboosted Fake Outs in VGC, though still slower than Pokemon like Weavile. Raichu also has access to Encore, which can lock your opponent into an unfavorable move, as well as other support moves like Nuzzle and Charm. Lightning Rod makes your team immune to single-target Electric-type moves, such as Thunderbolt and, most importantly, Thunder Wave. With Encore, Raichu can also lock its opponent into boosting its Special Attack via Lightning Rod. Furthermore, it has access to some decent attacking options, such as Hidden Power Ice, Thunderbolt, and Volt Switch, coming off its decent base 90 Special Attack.

However, it misses vital KOs, particularly on Garchomp with Hidden Power Ice, and it is pretty frail, so it is probably going to go down to one or two strong hits. It also really relies on its Speed to support allies, so if it drops due to Trick Room, Tailwind, Icy Wind, or something similar, it can't function as well. It also faces stiff competition from Pachirisu, which has access to Follow Me to redirect most hits and has better overall bulk, and Manectric, which can actually do something with the redirected Electric-type moves and, with its higher Special Attack stat, actually has a chance to KO Garchomp. Also, Liepard can steal its thunder with access to priority Encore, limiting the list of Pokemon that can outspeed it to just Talonflame.
