A Speed Duel box is playable on its own for standalone matches and can also be paired with other Speed Duel sets for head-to-head duels and expanded play.
Speed Duel collections include pre-built decks plus additional cards and new Skill Cards. Those extra cards and Skill Cards let you expand and upgrade your Speed Duel decks without needing to buy separate core sets.
The product is listed as suitable for ages 6 and up and includes a choking-hazard warning for small parts. Check the product packaging or listing for any additional, region-specific safety information.
