Raichu

Raichu is a decent wallbreaker with access to Nasty Plot, good coverage, and a high Special Attack. Raichu has excellent Speed that lets it outrun the majority of the PU tier, allowing it to revenge kill and clean up while still being able to wallbreak. Raichu is also good at taking advantage of forced switches by pivoting with Volt Switch or setting up with Nasty Plot. Raichu faces a lot of competition from the faster Zebstrika and Electrode, but it has the advantages of hitting harder and having access to Nasty Plot. It also faces competition with Electabuzz, which is bulkier, but Raichu is a little faster and has Nasty Plot. Finally, Raichu is very frail, meaning that it is easily revenge killed and has a hard time setting up.
