[Overview]
<p>With Wish's new mechanics along with Vaporeon's massive HP  stat, Vaporeon can really benefit your team by healing off any damage  that it may have taken. Vaporeon also got a nifty new toy in Scald,  allowing her to burn unsuspecting physical sweepers. She can still  utilize her Baton Passing capabilities with Acid Armor, Aqua Ring, and  her new move Work Up. However, because of more Pokémon who can hit  Vaporeon hard in this new generation such as Virizion and Thundurus as  well as older Pokémon such as Breloom, Vaporeon will have difficulty  walling to her full potential. In addition, she is susceptible to all  forms of entry hazard damage. Vaporeon is in for a tough time, but with  help from her teammates and by taking advantage of the new tools she has  received, she is fully capable of doing her job well.</p>

[SET COMMENTS]
<p>This set utilizes two of the fifth generation's gifts to  Vaporeon. With a defensive EV spread, Vaporeon can tank multiple hits  from opposing Pokémon. Scald serves as Vaporeon's STAB move and has a  handy 30% chance of burning the opposing Pokémon which is great for  crippling physically-based Pokémon who think they will be getting a free  switch-in. Wish heals an amount equal to 50% of Vaporeon's max HP to a  teammate. That, combined with Vaporeon's large base 130 HP stat, means  that she will be healing much of your team for at least 50%. Protect  serves as both a scouting move and ensures that Vaporeon gets healed by  her own Wish.</p>
<p>There are several options for the last moveslot. Roar is the  primary choice because Vaporeon can phaze out her counters such as  Ferrothorn and cause extra residual damage. Ice Beam is there for  Garchomp, Haxorus, Breloom, and any other Pokémon who resists Scald or  takes little damage from it. Finally, Toxic, in conjunction with  Protect, enables Vaporeon to stall out Pokémon who she walls. However,  this may clash with the burn chance from Scald.</p>
[Additional Comments]
<p>Haze can be used in the last spot for those last Pokémon  situations, but generally Roar is better since it forces them out.  Hidden Power Electric can be used to hit Gyarados but only scratches  other Water-type Pokémon due to its low Base Power., who are crippled  more by Toxic is generally a better answer to enemy Water-types. Heal Bell can be used for Vaporeon to be the ultimate  team supporter by allong it to both remove status and heal away any  damage taken. providing status removal in addition to its Wish-passing.</p>
<p>Due to Vaporeon's inability to really hurt Ferrothorn, he can  switch in and begin setting up entry hazards without much trouble.  Skarmory does a similar job except he uses Roost to heal off the damage  from Scald. Excadrill is a good choice to remove entry hazards with  Rapid Spin, as he is immune to Electric-type attacks. Vaporeon can also  switch into Fire- and Water-type attacks aimed at Excadrill. Breloom and  Virizion can be dangerous if Vaporeon doesn't catch them on the switch  with Ice Beam. Gliscor is a great counter for both of them as he has  Poison Heal to make him immune to Spore, has the Defense to take their  attacks, and can hit them back with a STAB Acrobat.<p>
<p>Ferrothorn also serves as a good partner. Vaporeon can easily  take the Fire-type attacks aimed at Ferrothorn whilst Ferrothorn can  handle both the Electric- and Grass-type moves headed Vaporeon's way.  Ferrothorn can also lay down entry hazards which Vaporeon can abuse with  Roar. Heatran is also an option to scare away Grass-type Pokémon such  as Ferrothorn. Vaporeon can also absorb the Water-type attacks aimed at  Heatran.</p>
[SET]

[SET COMMENTS]
<p>Not only can Vaporeon take advantage of her large HP stat to  pass Wishes, but also she can also use it to pass huge Substitutes to her  teammates on a Baton Pass chain. That, combined with her large support  movepool, enables her to fit many different roles. Baton Passing Acid  Armor is a good way to patch up inferior defensive stats, whilst Wish  allows Vaporeon and her team to create more Substitutes. Aqua Ring  slowly heals off any damage from Substitutes that your team may have  taken, acting like a weaker but more consistent Wish. The final moveslot  is to stop other Pokémon from stopping your Baton Pass chain. Scald  hits Taunters and any burns it may inflict make it harder for a physical  Pokémon to break Vaporeon's Substitute.  Roar can be used to phaze away  most phazers before Vaporeon is phazed away herself.</p>
[Additional Comments]
<p>The given EVs maximize Vaporeon's Baton Passing capabilities.  128 Speed EVs enable Vaporeon to outspeed positive-natured base 130s  with +2 Speed. 132 Defense EVs give a jump point with the given Bold  nature while 244 HP enables Vaporeon to make the largest HP Substitutes  she can without being entry hazard weak. Additionally, at +4 Defense,  Ferrothorn can't break Vaporeon's Substitutes with a 0 Attack Power  Whip. Vaporeon can also Baton Pass Work Up but generally Baton Pass  receivers are either physically or specially based so they don't have to  split EVs.</p>
<p>Gliscor and Celebi are great partners for Vaporeon because they  resist or are immune to Electric- and Grass-type moves. Gliscor can  also Taunt to stop opposing Taunters or phazers from ruining your Baton  Pass chain. Zapdos is also an acceptable choice because it resists  Grass-type moves and can Baton Pass both Agility and Substitutes whilst  Roosting off any damage taken. Espeon is a handy partner because she can  use Magic Mirror to bounce back phazing moves, Taunt, and  status-inflicting moves. She also has the ability to Calm Mind and keep  the Baton Pass chain running. Smeargle can pass anything you want, from  Ingrain to Shell Break to Gear Change.</p>
<p>As for a receiver, Metagross is always a good choice. It has  Clear Body so it can't be affected by Intimidate, has a Steel-typing so  it's immune to Toxic Spikes, and has powerful moves such as Meteor Mash  and Earthquake. Lucario is another potential choice except he's frailer  than Metagross but is still immune to Toxic spikes.</p>
[Team Options]
<p>Teams that are weak to Fire-, Water, and Ice-type attacks will  love Vaporeon's resistances and her Wish passing capabilities. Vaporeon,  combined with Gliscor and Ferrothorn forms a great defensive core  because of their fantastic synergy together. Gliscor can also use STAB  Acrobat and Earthquake to handle any Pokémon who Vaporeon may have  trouble with while Ferrothorn can lay down entry hazards, making and, thus, make  it harder for your opponent to break through this core. Additionally,  Ferrothorn appreciates Wish because he lacks reliable  recovery, and his low HP stat will gain huge percent increases from Vaporeon's massive Wishes.</p>
<p>A more offensive way to handle Grass- and Electric-type Pokémon  is to use Heatran and the various Dragon-type Pokémon. Heatran can  scorch Grass-types with his STAB moves while Vaporeon can absorb any  Water-type attacks directed at him. Garchomp can hit Electric-type  Pokémon with a STAB Earthquake while Vaporeon can easily switch into an  Ice Beam. Scizor is also a useful partner because he can hit Grass-type  Pokémon with a STAB U-turn and tank 4x resisted Grass-type attacks.  Vaporeon in turn can sponge Fire-type attacks and pass Wish to heal off  any entry hazard damage.</p>
<p>Vaporeon really dislikes Toxic Spikes because of the gradual  residual damage it brings. Forretress has good defensive synergy with  Vaporeon and can Rapid Spin away entry hazards. He can also lay down his  own entry hazards. Excadrill is a more offensive Rapid Spinner capable  of KOing many spinblockers with ease. With Roar on Vaporeon's side, she  appreciates entry hazard support. Forretress, Skarmory, and Ferrothorn  can all reliably set up entry hazards to slowly wear down the opposing  team.</p>
[Optional Changes]
<p>Surf may be used over Scald for more power in lieu of the 30%  burn chance. A Choice Specs set combined with Vaporeon's often  overlooked base 110 Special Attack is plausible, but is not without it's  downfalls. If you decide to use Hidden Power Fire, Vaporeon has  difficulty with Water-type Pokémon. If you use Hidden Power  Electric, Vaporeon has trouble with Ferrothorn.</p>
<p>Hydration is only useful if you bring along Politoed due to his  ability Drizzle. With Hydration, Vaporeon is best used on a stall team  centralized around rain. With rain automatically removing any statuses  inflicted on Vaporeon, she no longer has to fear Toxic. It also removes  the sleep status that Vaporeon succumbs to when using Rest. With it,  Vaporeon can boost her Defense using Acid Armor, stall using Toxic, and  hit any Pokémon immune to Toxic with Scald. An EV spread of 252 HP / 4  Def / 252 SpD with a Calm nature achieves the best overall defenses  after one Acid Armor boost. Unfortunately, Wish is incompatible with  Hydration, meaning Vaporeon cannot support her teammates as well.  Additionally, Vaporeon shares the same weaknesses with Politoed, so one  must be careful about switching.</p>
[Counters]
<p>Ferrothorn loves switching in on Vaporeon, as he can use Leech  Seed which, in conjunction with Vaporeon's massive HP stat, will heal  huge amounts of damage the he may have taken. From there, he can freely  set up entry hazards or attack with Power Whip. Skarmory can come in  easily because of Roost but getting burned by Scald severely hampers his  walling capabilities. Shaymin, Breloom, Virizion, Thundurus, Zapdos,  and many other Pokémon all can come in on Vaporeon and hit her with a  super effective STAB attack. Latios doesn't mind coming in on an Ice  Beam because of his massive Special Defense. From there, he can freely  launch Draco Meteors.</p>
<p>Without Roar, Vaporeon has trouble with boosting Pokémon.  Jirachi and Espeon can both utilize Calm Mind and Wish to slowly boost  up in front of Vaporeon. Jirachi's Steel typing means it's immune to  Toxic while Espeon has Magic Mirror to bounce it back. Reuniclus has  Magic Guard so he's immune to entry hazards and Toxic and can Calm Mind  in Vaporeon's face. Virizion can also Calm Mind and use Giga Drain to  heal off any damage it may have taken. Roobushin can use Bulk Up and  Drain Punch to set up and doesn't mind a burn due to Guts. Both Blissey  and Chansey can come in and put Vaporeon to a dead stop as Vaporeon  can't break either of them. They can also use Toxic to reduce Vaporeon's  walling capabilities and have Natural Cure, Aromatherapy, and Heal Bell  to rid themselves of harmful statuses.</p>
