[OVERVIEW]
* Klefki has a decent defensive typing in the game, resisting 11 types and weak to 2 types.
* The ability Prankster further Klefki's utility, having moves such as Thunder Wave to cripple fast sweepers and attackers such as Xerneas, Ultra Necrozma and Mega Salamence.I
* It can check Fairy and Dark types such as Xerneas, Yveltal and Darkrai
* Access to the rare Spikes allows it to perform as a hazard setter, as well as pressuring Defoggers and Primal Groudon with Toxic.
* Presence of Primal Groudon in the tier hinders Klefki's ability to function, as it cannot be hit with anything but Toxicl
* Klefki is also weak to common Ground and Fire coverage, and has no recovery aside from Leftover's passive recovery, allowing Pokemon it is supposed to check to wear it down easily.
* Klefki faces competition from other Steel types such as Magearna, Ferrothorn or Necrozma-Dusk-Mane. Magearna is a far better Xerneas check than Klefki and can reverse sweep foes, Ferrothorn having more bulk and longevity and being a better Spikes setter, and Necrozma-Dusk-Mane being able to check Xerneas, set up Stealth Rock and has offensive presence

[SET COMMENTS]
Moves
========
* Spikes is an important move for Klefki, damages grounded foes when they switch in, wear down Pokemon for Klefki's teammates.
* Thunder Wave is important for stopping fast Pokemon such as Marshadow and Mega Gengar,
* Shut down powerful attackers such as Mega Mewtwo Y, Ultra Necrozma, Xerneas and Mega Salamence.
* Toxic is important for chipping away at Pokemon which are not affected by Thunder Wave, such as Primal Groudon and Giratina.
* Play Rough stops Klefki from being Taunt bait, and hits Magic Bounce users such as Mega Sableye
* It also stops Dark types from setting up freely on Klefki without taking some damage.
* Foul Play is an option to possible kill Mega Gengar if paralyzed, and is the best direct attack to hit Psychic and Ghost types
Set Details
========
* Leftovers provide Klefki with passive recovery and is its only recovery method aside from Wish and Healing Wish.
* Prankster is a great ability which allows Klefki's status moves to be at +1 priority.
* Max HP and Special Defensive alongside a Careful nature maximizes Klefki's special bulk so it can check special attackers such as Yveltal and Xerneas.
* 252 HP / 4 Def / 252 SpD with a Calm nature can be used if Foul Play is used
Usage Tips
========
* Send in Klefki on relatively passive Pokemon such as Arceus-Water, Magearna, Lugia or Pokemon it checks such as Xerneas or Yveltal
* Use slow VoltTurn to allow Klefki to switch in and set up Spikes
* Put down Spikes when Klefki is against Pokemon which cannot deal much damage such as Magearna
* Klefki is taken advantage of a majority of the tier, so it should try and spread status and set up Spikes whenever possible
* Thunder Wave should be used to cripple fast threats such as Ultra Necrozma and Mega Salamence and provide speed control for slower threats in the back
* Look out for any Ground types as they are immune to Thunder Wave, predict them to come in and Toxic on the switch
* Upon switching in, Klefki should set up Spikes when the foe is not a threat such as Arceus-Water
* Toxic should be used to cripple bulky Pokemon such as Giratina and Ho-Oh for teammates to KO them
* It is also worth noting that using Thunder Wave immediately against fast threats is useful, as a misprediction can turn the tides of a game
* Klefki is not a reliable counter to most of its switch-ins, and should mainly be used to spread status among them and chip away foes with Spikes
* Do not set up hazards or spread status while there is a Magic Bounce user on the opposing team. Use Klefki’s teammates to weaken it until it cannot come in on Klefki’s Play Rough
* Klefki can be used to punish physical set-up Pokemon such as Mega Salamence or Necrozma-Dusk-Mane with Foul Play
* Be aware of opposing Ground and Steel-types, as they are able to use Klefki as setup fodder
* Although Klefki’s fairy typing allows it to be immune to Dragon-types, most Dragon-types such as Kyurem-White and Zygarde have Fire or Ground coverage, so Klefki should be aware of them
Team Options
========
* Offensive Pokemon that enjoy hazard stacking such as Geomancy Xerneas, Dragon Dance Mega Salamence, Extreme Killer Arceus, Marshadow
and Zygarde-C are also good partners, as Klefki can set up Spikes and intoxicate their checks
* Primal Groudon is a good teammate, as it sets up Stealth Rock alongside Spikes, resists Fire and Steel types, and helps double-check Xerneas
* Xerneas can help Klefki check Dark types such as Yveltal or Arceus-Dark
* Checks to Primal Groudon such as Mega Salamence or Zygarde are necessary, as Klefki struggles to do anything against
* These Pokemon also benefit from Klefki's ability to Paralyze or Toxic their checks and counters
* Wallbreakers such as Primal Kyogre, Yveltal or Lunala also benefit Klefki's Spikes as well as speed control from Thunder Wave
* Primal Kyogre in particular is able to take on Ground and Fire types such as Primal Groudon and Ho-Oh
* Hex users such as Giratina-O and Gengar-Mega benefit from Klefki's ability to spread status among opposing teams, and the latter can trap foes
* Bulky Shadow Tag users such as Gothitelle and Gothorita can trap Defog Arceus forms so Klefki's Spikes will stay on the field
[STRATEGY COMMENTS]
Other Options
=============
* A set with Swagger / Thunder Wave / Foul Play can be used, but as confusion has a low chance to hit, Dark types are immune to Prankster
moves and Primal Groudon being immune to Thunder Wave, this set is generally unviable.
* Dual Screens with Light Clay can be used, by Screens are generally very niche in the Uber tier and very hard to set up due to the presence of Primal Groudon
Checks and Counters
===================
**Ho-Oh**: Ho-Oh does not mind Toxic due to Regenerator and can threaten Klefki out with a powerful Sacred Fire. Defog varients are also able to get rid of Klefki's Spikes
**Ground Types**: Although they do not like to be intoxicated, Ground types are immune to Thunder Wave and can threaten Klefki out with their powerful Ground type moves. Primal Groudon can threaten Klefki with its STAB moves, Arceus-Ground can either use it to set up Swords Dance or threaten it with Judgment, while Zygarde-C can also use it to set up Dragon Dance or Coil. Furthermore, some Arceus-Ground and Zygarde-C sets run Substitute and can avoid a Toxic from Klefki
**Steel Types**: Steel types such as Ferrothorn, Dialga and Necrozma-Dusk-Mane are immune to Toxic and can threaten Klefki out with their Steel, Fire or Ground type coverage. They are also able to bring their own hazards and make Klefki take unnecessary damage
**Magic Bounce**: Magic Bounce stops Klefki's status moves and in return Klefki is unable to do much against them. It is also unable to 2HKO Mega Sableye with Play Rough
**Shadow Tag**: Shadow Tag users such as Mega Gengar or Gothitelle can stall Klefki out. Mega Gengar is able to 3HKO Klefki without Foul Play without much problem even though it dislikes Paralysis. Gothitelle can use Klefki to set up Calm Mind and kill it with Psyshock, as well as shrug off any status with Rest
