Exeggutor

Once widely considered to be the fourth best Pokemon in the RBY metagame as well as the best sleeper available, Exeggutor has recently suffered a drop in reputation and viability, though it remains a popular choice. A combination of Explosion, Sleep Powder, and Psychic, in addition to unique typing and solid base stats, makes it an easy pick for a large number of RBY teams. Despite the unfortunate Ice weakness, its resistance to Ground-type attacks makes it one of the most reliable Rhydon switch-ins; it is also the most reliable answer to the uncommon but threatening Slowbro. A combination of defensive utility and wallbreaking power earns Exeggutor a spot on many RBY teams; however, teams that already feature other sleepers may find it redundant, and its inability to recover damage can make it undesirable to some teams.
