The Custom Creatures Theme Deck for the Ninth Edition Core Deck was a preconstructed deck of forty cards. The theme for the deck was "Green." The purpose of the deck was to provide a ready out of the box deck (minimum 40 card deck) for players to play.
"Green" has a theme of Nature and Life.
The Theme Deck also included a customized strategy insert. The Theme Deck was considered "Advanced," and players were encouraged to get the "Core Game" to learn the game.
The insert recommended adding 8 Forests cards and 12 Green cards to bring the deck to 60 cards to play against more experienced players.
