This UX-21 Hellhound deck set is an advanced battle set for the BEYBLADE X series. The set covers three core combat positions and has a complete gameplay system: the main Hellhound is offensively positioned, with an orange-red transparent body with holy beast patterns, and a metal weight ring to provide strong centrifugal force and explosive attack power; Silver Wolf 9-70R is a balanced type, with a purple appearance and wolf pattern design, with balanced offensive and defensive attributes, suitable for a variety of combat situations; Wing Suspension 8-80B is a durable type, with a light green transparent body and outstanding rotation endurance. The three tops can be directly formed into a complete battle deck, and they also support splitting, modification, and matching with other series of parts, giving a high degree of freedom in gameplay.
