WWE Smack Down! is an Italian-market collectible card game produced by Tesla Distribuzione srl, a companion release to the same publisher's wider WWE card line. The SmackDown brand was separated from the general WWE product as its own named series, and evidence of at least three series exists: a base set, a second Fluo Variant Edition released in sealed packs of four cards, and a third series titled Ring dei Campioni (Ring of Champions). Cards featured Italian text and WWE SmackDown roster wrestlers. As with other Tesla products, distribution was confined to the Italian market. Exact publication dates, total card counts, and the complete roster of sets within the SmackDown line have not been consolidated in any publicly accessible source, placing this title firmly in the uncharted archive.
