Why cant a Pokemon enter a contest?

A Pokémon cannot enter a contest if it does not meet specific eligibility criteria, such as level restrictions or type requirements. Additionally, some contests may require Pokémon to have certain moves or characteristics that the contestant's Pokémon lacks. If the Pokémon is fainted or not registered in the contest system, it also cannot participate. Lastly, certain contests may have entry limits based on the number of participants allowed.
