Held: Increases the holder's Special Attack by 50%, but restricts it to the first move it uses until it leaves battle or loses this item. If this item is swapped for another Choice item via Trick or Switcheroo, the holder's restriction is still lifted, but it will again be restricted to the next move it uses.
(Quirk: If the holder is switched in by U-Turn and it also knows U-Turn, U-Turn becomes its restricted move.)
Trait: Water Absorb Absorbs Water moves, healing for 1/4 max HP.
Description: If you ever thought Jellicent was just a bulky Water-type that happened to be able to block Rapid Spin, think again. While its stats do not immediately show it, if you dig deeper and examine Jellicent's movepool and the Pokemon that tend to switch into it, it's quite clear that Jellicent can be a surprisingly effective lure and wallbreaker. The biggest catch behind a Choice Specs set is Jellicent's access to the precious Water Spout (which is barely seen on any Pokemon outside of the mighty Kyogre), as well as STAB Shadow Ball, which tends to hit its common switch-ins, such as Latias and Celebi, for super effective damage. Powered by Politoed's rain, Jellicent's Water Spout reaches an astounding 337 Base Power, rivaling the damage output of Choice Specs Palkia's Hydro Pump. Between Water Spout and Shadow Ball, it is difficult to find a Pokemon that can stomach Jellicent's assaults.
Options: As seen above, with some entry hazard support, Jellicent can OHKO or 2HKO most Pokemon in the metagame. In the third slot, Jellicent can utilize a secondary Water STAB attack to fall back on when its HP gets low. Surf is the most reliable option, while Hydro Pump is still immensely powerful in the rain at the cost of accuracy. Scald can be used for the burn chance, but it is generally not preferred, as the lack of power seems counterproductive on a wallbreaking lure.
The last slot is optional. Ice Beam allows Jellicent to hit Dragonite, which can be very problematic if it is at full HP (due to Multiscale), Virizion, and other Grass-types for super effective damage. Energy Ball, on the other hand, deals 4x effective damage against Gastrodon, which is immune to Water Spout and has enough Special Defense to take on Shadow Ball and Recover off the damage; it also hits Vaporeon harder than Shadow Ball does.
Counters: Obviously, Politoed is a great friend of Jellicent's, as it provides endless rain for Jellicent to spam Water Spout with. Blissey is also a fantastic partner, as it is immune to opposing Shadow Balls, can take Thunderbolts and Giga Drains with absolute ease, and can pass giant Wishes to heal Jellicent. In return, Jellicent can switch into Fighting-type attacks that are aimed at Blissey. Latias, Celebi, and Virizion can easily switch into Electric- and Grass-type attacks aimed at Jellicent. As mentioned before, Dragonite can be a very problematic Pokemon to deal with if Stealth Rock is not up, as Multiscale allows it to tank Water Spout and potentially Ice Beam with a lot of Special Defense investment. It can then use its powerful Dragon-type STAB to heavily damage Jellicent. Jirachi, Bronzong, and Skarmory are all excellent checks to Dragonite.
