Movesets et sets compétitifs de Ralts

This is the only set that Ralts can successfully accomplish anything with without support from others. When leading with Ralts, Trick Room is the primary move that it should aim for before it faints. After successfully activating Trick Room, Ralts can either choose Memento or Destiny Bond, as it can't do anything else but sacrifice itself. With Memento, Ralts makes opponents completely useless, giving you a free turn as they will likely switch out. Destiny Bond can be used effectively if the opponent uses an attacking move, taking down an important member of the opponent's team while you only have to sacrifice Ralts. Protect avoids the use of Fake Out from the opponent so Focus Sash remains intact, or it can be used to get a glimpse at what set your opponent is using. Ralts is not able to achieve anything else besides this. The EVs, IVs, and nature ensure that this set can be used effectively. Ralts can't function properly without Focus Sash, so if you're not leading with Ralts, it is recommended that you lead with a Taunt user to prevent entry hazards being set. Trick Room sweepers such as Munchlax, Makuhita, and Clamperl are appropriate teammates to take advantage of Trick Room.

This is the only role that Ralts can do somewhat well. It is also a unique set for Ralts, as no other Pokemon has the ability to learn the combination of Trick Room, Destiny Bond, and Encore. Trick Room takes advantage of Ralts's low Speed. If you lead with this set, or if you are able to keep entry hazards off of the field, then Ralts is guaranteed to set up Trick Room thanks to its Focus Sash. From there, Ralts can use Memento, Destiny Bond, or Encore to great effect, as it outspeeds almost every Pokemon in Little Cup under Trick Room. Memento will allow you to set up a very powerful Trick Room sweeper. If the opponent attacks, Ralts can use Destiny Bond to take the opponent down with it, thus scoring a free switch in for your Trick Room sweeper. Encore is there to make your opponent avoid using a non-attacking move, as doing so will also give you a free switch in for your Trick Room sweeper of choice. Ralts really has nothing else going for it, so this is all it has. Reflect and Light Screen could be used to support your team, but good luck finding time to use them. The IVs, EVs, and nature are all geared toward using Trick Room to its fullest extent. Ralts cannot function effectively without its Focus Sash. Therefore, if you are not using Ralts as a lead, it is necessary to use a Rapid Spinner or Taunter to prevent your opponent from setting up entry hazards on the field. Trick Room sweepers are obviously necessary to take advantage of the Trick Room that Ralts sets up, as it cannot do damage effectively by itself. Some examples of these sweepers are Cubone, Munchlax, and Clamperl. Other Trick Room set-up Pokemon, such as Bronzor, are recommended to help set up Trick Room again after the initial Trick Room wears off.
