This may come as a surprise to some, but not all pain relievers are the same. In fact, the difference between many over-the-counter pain relievers can have various effects on your body. People sometimes refer to a specific over-the-counter medication (OTC)--Tylenol, Aspirin, Advil, etc.--even if they donât have a specific brand in mind. The U.S. Food and Drug Administration (FDA) considers all three effective for the same minor aches and pains.
Fairy Type Pokemon are countered by Poison Type. For Example, Muk (Poison type) will deal increased damage to Clefable when using any Poison Moves against him in Gym Battles. However, it will also take decreased damage when attacked by Fighting, Dragon and Dark moves.
An example of a non-fully evolved pokemon being used in VGC because of it's ability is Clefairy. It's ability Friend Guard is lost if it evolves in to a Celfable. The ability is good enough that players sacrifice the other advantages of Clefable and instead use a Clefairy that holds Eviolite.
