Pokemon Cruel Traitor XY11 1st Edition Japanese Booster Pack

Step into the darker side of battle with Cruel Traitor, a Japanese expansion from the Pokémon Trading Card Game’s XY BREAK era. Released in Japan on June 17, 2016, this set launched alongside its counterpart Fever-Burst Fighter, together forming the foundation of the English expansion Steam Siege. 

Featuring a strong focus on Psychic- and Dark-type Pokémon, Cruel Traitor highlights powerful forces like Mega Gardevoir and introduces strategic depth through BREAK Evolutions and dual-type mechanics. With striking Japanese-exclusive artwork and a theme centered around betrayal and control, the set brings a more tactical, calculated edge to battles.

Whether you're collecting iconic XY-era cards or building a competitive deck, Cruel Traitor delivers a compelling mix of power, strategy, and sinister style—perfect for trainers who prefer precision over brute force.
