[SET COMMENTS]
<p>Like many of its fellow Psychic-types, Gardevoir has access to both Reflect and Light Screen. What sets Gardevoir apart as a dual screener, however,is its Trace ability
and respectable Special Defense(delete this since Uxie, Cressalia, and Bronzong have more, and Jirachi isn't far behind so this doesn't set it apart), which give
s(how did nobody catch that :p) it many opportunities to switch into battle, and its wide supporting movepool beyond the two screens.</p>
<p>
In addition to Reflect and Light Screen(this isn't really required, since we already know you mean in addition since there is no slash next to either of these moves), Gardevoir can use a myriad of other useful supporting moves. Healing Wish is extremely helpful in the later stages of the battle, when sweepers have taken hits and are generally quite low on health. It is the ultimate sweeper rejuvenator, healing all HP and status at the cost of Gardevoir fainting itself. This also has the advantage of not wasting any additional turns of the screens, and gets a sweeper in straightaway to make the most of them. Memento works similarly, but instead of healing another team member, it sharply reduces both of the opponent's attacking stats. This is perfect in giving a set up sweeper a free turn, as your opponent will be loathe to keep in their weakened Pokemon.
Memento is not constricted to use later on in the game, but it doesn't have as significant an effect as Healing Wish does(this sentence isn't required, and I don't think it would be missed if deleted). On the other hand(delete, doesn't flow right to me), Destiny Bond is an option if you are looking for Gardevoir to contribute more to the team's offense, as it can be used to take an opposing Pokemon down with it.</p>
<p>Even without any investment, Gardevoir sits on a respectable 286 Special Attack. This makes
a(no articles here) STAB Psychic a good choice as the last move, being able to deal with
weakened Pokemon(I don't think Infernape needs to be weakened so you can get rid of this too) such as Infernape if need be. Will-O-Wisp is useful as an additional buffer against physical attackers, and helps to make up for Gardevoir's weak Defense. It is also useful as it is a permanent solution to the likes of Scizor and Tyranitar, meaning
they fail to be a threat to both Gardevoir and the rest of the team once burnt(this isn't necessary, nor always true, especially against incredibly weakened or low HP Pokemon). Alternatively, Wish grants Gardevoir a way of keeping its own health high to set up screens repeatedly, and can be passed on to other Pokemon on your team to heal them without having to sacrifice Gardevoir.</p>
<p>Gardevoir has a massive movepool and a lot of different options can go into this last slot. Taunt is another really helpful move to have on a dual screener - it stops threatening sweepers from abusing Gardevoir's lack of offense and setting up on it, as well as preventing other Pokemon with weak offenses from accomplishing anything significant against Gardevoir. Used in conjunction with Destiny Bond, it can force opponents to attack, allowing you to take down an opposing Pokemon with a lot more reliability. If you plan on going direct to a sweeper after setting up the screens, Taunt will also prevent crippling status moves from being used against them. As far as Gardevoir's own status options go, Hypnosis can be used to temporarily remove any opposing Pokemon from the battle if the accuracy doesn't let you down, and Thunder Wave slows the opponent down so Gardevoir can screen up before they attack, as well as potentially giving Gardevoir free turns to go about its job.</p>
<p>Trace provides plenty of opportunities to switch in in OU, since many Pokemon can have their abilities used against themselves. Jolteon, Heatran, Vaporeon, and Electivire will not be able to hit Gardevoir with their primary STAB attacks, meaning they will more than likely switch. By Tracing Natural Cure, Gardevoir fears very little from setting up on Celebi or Blissey. If Scarf Magnezone
is locked into an attacking move(even if it is not Choice Scarf, it will still be locked in right?), Gardevoir can come in and trap it with a Traced Magnet Pull, forcing the opponent to helplessly stay in as you go about giving your team all the support it needs. Since the majority of these Pokemon are special based,
and Gardevoir itself leans more towards sponging these special attacks(not necessry, and it's more of a 'leap' than a lean :p), the EVs of the set are designed to let it do so. The Speed EVs allow Gardevoir to outspeed Adamant Scizor, allowing it to set up a Reflect before Scizor hits, easing the damage against the metal bug's Choice Band U-turn so that it no longer OHKOes. Alternatively, a faster spread with 200 Speed EVs allows Gardevoir to get the jump on Jolly Tyranitar and many of the Pokemon that EV to specifically outspeed it, and being able to go first against common Pokemon such as Celebi is very helpful when running Taunt. To get this faster Speed, EVs should be taken from Special Defense, as Gardevoir's low HP needs all the bolstering it can get. For the item choice, Light Clay is definitely the way to go, as it greatly extends the duration of the screens.</p>
