Does the Opponent Get a Prize if a Pokémon Knocks Itself Out?

Self-Inflicted Knockouts in Pokémon TCG

In the Pokémon Trading Card Game (TCG), if a Pokémon knocks itself out due to self-inflicted damage, the opponent does indeed get to take a prize card. This is consistent with the game's rules regarding knockouts. When a Pokémon is knocked out, regardless of whether it was done by an opponent's attack or by its own effects, the opponent is rewarded with a prize card. This rule applies to any situation where a Pokémon's attack or ability results in its own knockout, such as damaging itself during an attack.
