Jynx

Jynx's role remains virtually unchanged from its job in standard OU play—using Lovely Kiss on Psychic-type leads, absorbing or blocking sleep for its own team, and fishing for a freeze if given the chance. What changes, however, is the relevance of that role. Jynx remains just as capable at inducing sleep, but teams that utilize sleep-inducing physical attackers make it much harder for Jynx to absorb sleep. Jynx's horrendous physical bulk lets Pokemon like Persian and Snorlax pulverize it after Jynx is paralyzed, preventing it from being an effective sleep blocker. Jynx also struggles to remove paralysis via Rest against these teams, as using it allows every physical attacker free entry. This essentially means that against teams that employ physical sleep inducers, Jynx's only use will be to induce sleep early and to potentially annoy Pokemon like Chansey, without ever getting the chance to block or absorb sleep for its teammates. Jynx also performs horribly against sleep leads that outspeed it, such as Gengar and Persian. Hypno also competes with Jynx as a Psychic-type sleep inducer, which trades out accuracy on its sleep move for access to Thunder Wave and Amnesia, which makes it much deadlier later in the game. Fortunately, though, Jynx still manages to perform well against teams that still use traditional methods of inducing sleep, like Sing Chansey or non-Double-Edge Exeggutor. This relegates Jynx to being a more matchup-specific Pokemon rather than one of the most consistent leads in the tier.
