From Bulbapedia, the community-driven Pokémon encyclopedia.
Crowned Tiger is the name of the deck used by Tsubasa Nakamura, the Junior Division Champion in the 2009 World Championships. The deck uses primarily Psychic-type Pokémon, utilizing a limited number of Lightning-type and Darkness-type Pokémon. The Pokémon are mostly Pokémon SP and features no evolutions. The deck is based on the LuxBox archetype, popular during the 2009-2010 season.
Crowned Tiger is one of the four 2009 World Championships Decks, released on October 28, 2009. Each deck comes packaged with a 2009 World Championships Booklet. Each card features a silver border, Nakamura's signature, and limited edition 2009 World Championships back. None of the cards are tournament legal.
Tsubasa Nakamura achieved amazing results and rose to the level of World Champion with his notably relentless deck that uses Skuntank 's Poké-Power to Poison at will, then Toxicroak to really pile on the extra damage. And with Luxray LV.X and its Bright Look Poké-Power to change out his opponent's Active Pokémon, Crowned Tiger truly rules!
