Hello Smogon! I've been running a Gardevoir on my UU team for a while now, and I think I've found a niche that only Gardevoir is suited to; stopping Rain Dance teams in their tracks. Every single time I've run into a Rain Dance team, I've either stopped it cold with Gardevoir, or been played by something weird like 252 speed Floatzel, so I thought it was worth a mention on the analysis at least. I'm prepared to make changes, but so far it's served me well.

Why does this set deserve to be on site?
Well, I think that's enough about the set for now. Let me know if this can be made more efficient, I'm not entirely sure about what the best options are for the third and fourth moves, but those options have served me well. And don't be too harsh! At least Gardevoir has a niche here and isn't trying to be a trick-scarf anti lead! :P

Item: Life Orb
Ability: Trace

Why does this set deserve to be on site?
- No current Gardevoir sets address UU, Rain Dance, or Life Orb.
- Not outclassed by Golduck or Porygon2; Gardevoir can deal with more threats directly, at the cost of not being able to switch in as easily.
- Wide movepool allows for use outside of rain/sun, can abuse Trace with Energy Ball and Will o Wisp physical switch ins.
- Can beat any rain sweeper 1-on-1, outspeeding all thanks to Trace and EV spread. Only Ludicolo survives an attack.
- Also matches up well against sun teams thanks to Signal Beam and Psychic.
- Energy Ball > Grass Knot in all situations. Thunderbolt is more effective against standard, eg Milotic and Moltres.
- Can't switch in on water attacks; double switching against mixed sweepers can be helpful for getting Gardevoir in.
- If Dugtrio revenges a pokemon, Gardevoir can trap and kill it using Trace, always surviving an attack from LO Dugtrio.
- Stealth Rock can impede Gardevoir's progress by preventing a clean kill on Ludicolo, but is less common on rain teams.
- Can use lots of additional support moves, such as Encore, Mean Look, Wish, Reflect, Hypnosis and Thunder Wave in the fourth slot.
- Also has access to lots of coverage moves outside of weather, such as Shadow Ball and Focus Blast.
- You /can/ run an Expert Belt, but that makes Thunderbolt mandatory. Signal Beam still hits Ludicolo hard.
- Donphan and Cloyster make good teammates; they can rapid spin, wall physical attacks and provide their own entry hazards. Lead Cloyster can prevent Uxie from getting up Rocks.
- Priority users can clean up kills; Ambipom, Hariyama and Hitmontop all synergise well, as do Donphan and Cloyster, although Ice Shard might lose power against rain teams.
- Fire types can make the most of a lack of rain dance, such as Arcanine, Houndoom and Blaziken.
- Pursuit trappers can trap and kill Gardevoir, but are uncommon on rain teams, and signal beam / focus blast can be decent against them.
- Houndoom walls Gardevoir without Focus Blast, and can set up on the switch.
Why does this set deserve to be on site?
- There are absolutely no sets on-site at the moment that use Life Orb, address UU gameplay, or talk about combating Rain Dance with Gardevoir at all.
- Gardevoir has the potential to beat /any/ standard UU rain sweeper 1 to 1, and can kill most of them before they have a chance to react.
- Gardevoir also matches up fairly well against sun teams, outspeeding and OHKOing Shiftry, Exeggutor, Tangrowth and Leafeon with Signal Beam, and eliminating Venusaur, Victreebell and Vileplume with Psychic.
- Gardevoir also has a fair amount of use outside of weather, thanks to Trace allowing for a lot of free switches, and good synergy between its powerful attacks
- The only direct alternative is Porygon2, and in this situation, Gardevoir is faster, more powerful and has a better movepool, although it's admittedly less bulky.
- The EV spread is complex, but justified. 204 Speed EVs and Timid gives Gardevoir 271 Speed, which is just enough to outpace 16 Speed Adamant Floatzel, which is the fastest set Gardevoir can practically outpace. It's also a few points faster than 252 Adamant Qwilfish, which is justification not to go below. 200 SpA EVs guarantees that Gardevoir will OHKO everything but Ludicolo with Energy Ball, and will OHKO Qwilfish with Psychic with ease. 88 HP and 16 Def EVs provide as much bulk is possible against Aqua Jet users, and minimise the amount of damage that Gardevoir takes from Life Orb.
- Psychic is there for STAB, and is your only option against Ludicolo, who is unfortunately your biggest nemesis. Thankfully, if Gardevoir does not come in on entry hazards, it will always survive a Surf from Ludicolo (this does /not/ mean you can switch in on Ludicolo, or any other sweeper) , and can KO it with two Psychics or Signal Beams. However, it will die from Life Orb recoil on the second Psychic about 70% of the time.
- Energy Ball was chosen primarily because it can be OHKO all UU rain sweepers (apart from Qwilfish, who dies to Psychic) but also retains a ton of use outside of the rain. Gardevoir can switch into Claydol's Earth Power, Lanturn's Thunderbolt/wave or even Quagsire's Waterfall, and deal a lot of damage with Energy Ball in situations where Thunderbolt would be useless. However, Thunderbolt can be used if you want to use Gardevoir to counter different threats, or if you want to use a different item/ev spread whilst ensuring the same KOs.
- Signal Beam is the primary option for the third slot, since it's your best option against Ludicolo, Uxie, Alakazam and sun teams in general. It can also OHKO Absol, who you outspeed if it goes for a Pursuit. However, Focus Blast can also be used since it synergises well with Gardevoir's other offensive moves, and can damage Steel types such as Steelix and Registeel. This is the best option if you're less concerned by sun teams, or rather the lack of them. :P
- The last slot is reserved for a support move. Protect is one of the best options, since you can use it to stall out Rain turns, scout for priority moves and Pursuit, and can let you dodge Explosion with panache. However, Taunt is also worth mention as an offensive option; since Gardevoir outspeeds most rain setup pokémon, it can also be proactive and prevent Rain Dance from being re-established later on. You can also use Taunt in conjunction with Destiny Bond, if you use it in the third slot, but beware the lack of coverage from sacrificing Signal Beam / Focus Blast. Reflect is also worthy of mention; should you have time to set one up, it foolproofs you against priority attacks, ridiculously fast Floatzel/Qwilfish sets, and physical threats in general, whilst being more accurate and less restricted than Will o Wisp.
- A Life Orb was required to get a lot of KOs without using a Modest nature, which would have made Gardevoir too slow to deal with the standard Floatzel. Using an Expert Belt can work if you choose Thunderbolt over Energy Ball, but prepare to be underwhelmed outside of rain, since Energy Ball hits a load more threats in UU.
- It's worth noting that after Dugtrio's revenged a pokémon, this Gardevoir can come in, trap it with Traced Arena Trap, and OHKO it with Psychic or Energy Ball, without fearing death from Life Orb dugtrio at all, thanks to the EVs. :D Likewise, you can trap Magneton and Probopass with Traced Magnet Pull, but you won't be able to reliably 2HKO Magneton without Focus Blast, and Probopass laughs at you without it.
- Gardevoir hates switching into entry hazards when trying to combat rain teams; Stealth Rock prevents Gardevoir from finishing off Ludicolo, trying to get a Reflect on Kabutops, or surviving an encounter with Dugtrio. Donphan and Cloyster can both be useful, possessing good physical bulk, being able to rapid spin, and being able to ice shard Dugtrio and Ludicolo.
- I only just spotted that Gardevoir can learn Grass Knot, but being UU, Energy Ball out-damages Grass Knot in every case it needs to. Gorebyss can survive Psychic or Grass Knot, but not Energy Ball. You might miss the extra damage against Claydol and Cloyster, but that's it, and why the hell are you staying in on Cloyster?
- If you feel that one of your moves is never helping you, feel free to replace it with another slash, they all work well. Encore, Mean Look, Hypnosis and Thunder Wave might also come in handy, but I haven't tested these. Hypnosis might rock against Ludicolo and stuff, but the accuracy will betray you half the time, which is why it isn't listed.
- As said before, Donphan and Cloyster are nice supporters. They can also set up entry hazards of their own, which can make Gardevoir more comfortable to run an alternative spread/item. Cloyster can be run as a lead, and can keep rocks off the field with rapid spin to ensure that Gardevoir can check threats uninterrupted.
- Kabutops makes for an interesting lead, being able to put up hazards, rapid spin or explode if needed, and can make a last minute response to rain teams with a quick Stone Edge.
- A priority move user can often be helpful, if Gardevoir faints just short of a kill thanks to Stealth Rock or Spikes. Hariyama, Hitmontop and Blaziken all synergize well, as does Spiritomb.
- Since Gardevoir can ruin a Rain Dance team's chance to sweep, having something to make the most of it can also be nice. Houndoom can work well, as can Blaziken.
- Using Light Screen or Reflect can let Gardevoir actually switch into a sweeper, meaning that you won't have to lose one of your pokémon at all to Rain Dance. Be aware this limits Gardevoir's use in much the same way as Stealth Rock.
- The unexpected; weird rain sweeper sets can catch this set by surprise. Jolly Qwilfish only exists to piss Gardevoir off, and I saw a 252 Speed Floatzel earlier today. Unfortunately, nothing can be done against ridiculously fast sets without a Scarf, which limits Gardevoir's power in taking them out, as well as late-game use.
- Pursuit trappers, obviously. Although Focus Blast can do decently against Drapion and Skuntank, you haven't got a chance in hell against Spiritomb.
- Houndoom. Takes nothing from Psychic, and almost nothing from Energy Ball, and can switch in on Will o Wisp to aid a sweep. Focus Blast can be helpful, though.
- Chansey can wall this (well duh) but I'm not really sure what she'd be doing on a Rain Dance offense team. That said, you can switch in on her with impunity, Reflect, and switch back out without fear of status, thanks to Trace.
Well, I think that's enough about the set for now. Let me know if this can be made more efficient, I'm not entirely sure about what the best options are for the third and fourth moves, but those options have served me well. And don't be too harsh! At least Gardevoir has a niche here and isn't trying to be a trick-scarf anti lead! :P
