Players participating in the competition will learn how to breed competitive Pokemon. To avoid tedious work, many players choose to buy 6 IV Shiny Pokemon. It is relatively easy for players to find powerful Pokemon in Pokemon Swords and Shields, but breeding is still the best way to obtain competitive Pokemon.

Before breeding, it is important to have judgment. The judgment function allows players to view the personal values of Pokémon, usually called IV. These IVs will determine various statistics.

A competitive Pokemon will usually have at least five attributes with a perfect IV. Buy 6 IV Shiny Pokemon is the fastest way for newbies. Without the judgment function, the IV cannot be viewed. To obtain the function of judgment, the player must become the Galar champion and then defeat the first three floors of the tower. Since then, Leon will provide players with referee functions.
