Jynx

Jynx has a lot of unique features that differentiate it from other Psychic-types such as Alakazam and Starmie. For one, Jynx is the second fastest sleep inducer after the unreliable Gengar, making it a fantastic potential lead option that can incapacitate its checks by making them fall asleep. STAB Blizzard also allows Jynx to win the matchup versus Pokemon such as Exeggutor, Rhydon, and Zapdos. This is all in addition to the standard expectations of a fantastic Psychic-type: access to the powerful STAB Psychic and a high Special stat. Jynx also has its faults, though. Despite its key resistances to Ice- and Psychic-type attacks, Jynx can become easily trampled over by physical attacks, namely from Normal-types such as Tauros and Snorlax, due to its pitiful HP and Defense stats. While its key resistances to Blizzard and Psychic may say otherwise, the main way Jynx provides defensive utility is being the switch-in for predicted sleep-inducing moves. Additionally, nearly all teams run at least two solid checks to Jynx between Chansey and either Starmie or Alakazam, sometimes both. Due to the omnipresence of these checks, their access to Thunder Wave and reliable recovery, and Jynx's susceptibility to paralysis and being worn down over time, Jynx's role is undermined. Jynx can use Rest to restore its health and alleviate its paralysis, burning off sleep turns against Pokemon that can't do much back to it like a paralyzed BoltBeam Starmie. However, doing so opens itself up to a slew of physical attackers such as Tauros and Snorlax that can freely switch into it while it's asleep.
