Scooby Doo Expandable Card Game

Scooby-Doo Expandable Card Game is an Upper Deck kid-market release from the What's New, Scooby-Doo era, when the Warner Bros. animated revival had pulled the Mystery Machine back into Saturday morning rotation.

The game

Released in 2003 by Upper Deck, Scooby-Doo ECG is a two-player mystery-solving duel where each player builds a team (Scooby, Shaggy, Velma, Fred, Daphne, plus various cameos) and races to unmask the villain behind a Mystery card before the opponent does. The ECG format means it shipped with pre-constructed starter decks and fixed expansion packs rather than random boosters.

The context

Upper Deck had been running Yu-Gi-Oh! in English since 2002 and had an interest in kid-friendly TCGs that could shelve next to that product. What's New, Scooby-Doo was airing on Kids' WB at the time and the merchandise push was substantial. The ECG format was a response to parent pushback against random-booster collectible spending.

The collector angle

The base set and the Haunted House expansion make up the full print. Foil Scooby and Shaggy cards from the base set are the visible chase. The Meddling Kids promo pack from a 2003 Kids' WB tie-in event is the trophy item and is genuinely hard to find because it was only distributed through TV-show mail-in redemptions. Because it was a mass-market kid product, sealed boxes are still turning up in liquidation inventory twenty-plus years later.
