[Overview]
<p>Cleffa is one of the  weakest Pokémon in Little Cup, due to its generally mediocre stats. The  most notable of Cleffa's flaws is its ability to die to almost just about every attack in Little Cup. This set uses just this downside to its advantage. Due  to Cleffa's horrific stats, it usually dies in just 1 turn, but this  set uses this ability along with Cleffa's Magic Guard to its advantage  by getting at least 1 kill. Hail and Sandstorm help this set run effectively as they buffet the opponent and don't affect Cleffa, which allows it to get off a kill. (We aren't talking about a set here. This is a Overview. I'll rewrite for you so delete this entire paragraph and use the other one below.)</p>
 <p>Cleffa is one of the weakest Pokémon in Little Cup, due  to its generally mediocre stats. The most notable of Cleffa's flaws is  its ability to die to just about every attack in Little Cup. Moreover, Cleffa cannot utilize a majority of its otherwise amazing movepool due to its low stats.  However, access to the exclusive Magic Guard, which makes Cleffa immune  to all indirect attacks, gives Cleffa a certain niche: as an annoying  Endeavor user. Stay clear from this Pokemon unless you want to try  something daring but new.</p>

[SET COMMENTS]
<p>This  set takes advantage of Cleffa’s weak base stats in order to take down at least one Pokemon with it.   and uses them in a manner such that  Cleffa takes at least 1 Pokémon   down with it. Cleffa's Magic Guard makes sure that it doesn't get   affected by entry hazards such as Stealth Rock indirect damage from the likes of Stealth Rock, aside from letting its which allows Cleffa to keep its Focus Sash in tact. remained enabled through entry hazards, its ability also   prevents it from getting affected by weather effects such as hail. In   this case this is very important. Endeavor is to should be used on the first   turn since  with Cleffa's incredibly low Speed and defenses, it will likely be  smashed down right off the bat. By then, Cleffa's Focus Sash will  activate, and the opponent will be left with 1 HP, which is enough for  it to be KOed by residual damage from hail or sandstorm. Protect  allows Cleffa to scout for potential counters, such as Trick users, and  also to look out for what move the opponent is using when Cleffa has no  use left after using Endeavor. Both Toxic and  Thunder Wave are useful for crippling Pokemon that are immune to  Endeavor, hail, and/or sandstorm, such as Gastly, Swinub, and Diglett. Lastly, Encore can prevent opponents, such as Substitute and stat boosting users, from setting up on Cleffa. By doing this, Cleffa has another chance to KO the switch-in with Endeavor. since Cleffa has low speed EVs and a very low base Speed,  it will  get outsped and due to its 0 defense EVs, its Focus  Sash will be  activated. The  8 Speed EVs help be faster than minimum Speed  Bronzor.   This way  endeavor will make sure that Cleffa's opponent is  also left  with 1 HP.  This set can effective only if it is  used in  conjunction  with Snover  due to Snover's permanent hail, allowing the  opponent to  get buffeted  by the hail and thus loose the last HP that it  had  remaining while  Cleffa survives due to Magic guard.   To counter setting up Pokémon, Endeavor can be   highly effective,   since if another Pokémon is switched in and it starts   setting up, the   same strategy can be used to Endeavor, allowing  them to  be at level  HP  of 1 and then letting hail KO the opponent, this  would  only happen  on  a rare occasion when the opponent decides to set  up. The following   examples can be applied with Hippopotas' Sandstorm too. The Attack EVs are present to allow for  users to add an attacking move into the set as a replacement for  Encore. (Wrong area, irrelevant/repetitive information, or in need of rewording.) </p>
[ADDITIONAL  COMMENTS]
<p>If in the rare case a  user decides to set   up on  Cleffa, Encore helps lock the opponent on  to the same move   allowing  Cleffa to have another free KO if a switch  is not made. Toxic   and Hail  are just filler moves. During set up,  aside from Encore,  Toxic  or Hail  (if Snover is not used) can be used.  (Most are in the wrong area.) Hail  can be used over the third slot if hail isn't present, but finding time  to use it is hard. It's better to just put Snover in your team and  preserve its health throughout the match. This set not only  works  with Snover's hail, but also with Hippopotas's Sand Stream ability that  causes a  sandstorm. Sadly, there are more Pokemon immune to sandstorm than hail, making it a lesser option. The 8 Speed EVs allow Cleffa to outspeed and Endeavor Bronzor in case it switches in after Cleffa has taken down a Pokemon. Cleffa  could act as support for either one of the  sets, it  won't change  much. This set is one of the only viable sets  that Cleffa  can run  effectively, due to its bad stats and its  extraordinary ability  to die  to every threat in Little Cup.</p>
[Team Options]
<p>As  the name of the  set suggests, this   set is weather support, so a Pokémon that sets up  weather or has an   ability that runs weather is  a requirement for this  set to work, with   Snover’s permanent hail  allowing Cleffa’s Magic  Guard to work. Snover is mandatory to make this set  work, due to its ability to setup permanent hail. Hail helps pick off  every Pokemon excluding Ice-types after they have been Endeavored. Snover   is not the only viable team option, as other Pokémon that have abilities of   never-ending weather abilities such as Hippopotas's sandstorm is also a   plausible teammate tool.  Any Pokémon with Pluck, (comma) such as Taillow, (comma) would can be useful for countering Oran Berry users so that Cleffa's strategy doesn't get ruined., (remove comma) such as  Taillow.  To counter Oran Berry users, this way the Cleffa strategy can  be used  without being absolutely countered by Oran Berry. Oran berry is  a highly  used berry and this causes several problems for this set  unless you  have a Pokémon with Pluck. Due to this set being only requiring specific  weather  support, aside from weather setting up Pokémon, (remove comma) this set has no  real necessary  teammates.</p>
[Optional Changes]
<p>Encore  could be replaced by an attacking  move, but in that case, Cleffa would  become obvious set up  bait. (It's one of the main options...) Cleffa has a great amount of other options, but sadly it can't make good use of them generally due to its pathetic Speed.  Trick can be used to steal the opponent's item after Focus Sash has  been used, but Cleffa will usually die before pulling it off. Wish has  the same problem, but it can be awarding if there's time. With base 45  Special Attack, Cleffa could use special attacks such as Shadow Ball,  Flamethrower, and Icy Wind, but it's better off destroying foes with  Endeavor. Thunder Wave in conjunction with Swagger or Sweet Kiss can be  annoying, and could even allow Cleffa to use Endeavor again. Lastly, if you're lucky enough, Sing can put a foe to sleep.</p>
[Counters]
<p>Cleffa being  weak  is easily countered by   anything that is not affected by snow, such  as  another Snover. This   would make Cleffa’s set absolutely ineffective   and useless. Oran Berry   is also a major counter for this set as Oran  Berry is activated before   hail and therefore the user will restore its  health and the hail damage   will be minimal and will allow Cleffa to  get KO'd the next turn and   again making the set useless. Ghost-types such as Gastly and Drifloon are extremely good the best  counters  to this set as they will are not be affected by Endeavor. (period) They can also use Substitute to block Cleffa's status moves and then attack, but they must beware of Encore. Oran Berry users are also major counters to Cleffa as the item activates before hail's damage takes effect, which allows the users to KO Cleffa afterward. Other  "counters" are generally less effective as they will have their HP  lowered to 1, but otherwise it's a step forward to defeating Cleffa.  Pokemon immune to hail, such as Snover and Swinub, are decent counters  to Cleffa. Likewise, Pokemon immune to sandstorm can counter Cleffa, but  to a lesser degree as most Cleffa users do not pack Hippopotas. If  you lack any of the mentioned counters, then the best option is to  sacrifice your current Pokemon to take down Cleffa's Focus Sash and KO  it with another Pokemon. and  thus will let  Cleffa die to any of their moves.</p>
