Main article: Overflow Deck (GB2)

Overflow Deck (Japanese: オーバーフローデッキ) is the first deck played by Nicholas. The first time this battle is contested, there is no prize other than the opportunity to battle against Isaac; after the player defeats Isaac and GR4 leaves the area, defeating Nicholas while he plays this deck will get the player a Beginning Pokémon booster pack.

Nicholas can be fought from the beginning of the game. At the beginning of the game, the Lightning Club is captured by GR4, who makes Nicholas and Isaac serve her and battle the player. Nicholas uses this decklist for that match. Later in the game, Nicholas will upgrade his deck and this deck will not be available to battle against from then on.

This deck is also available in Autodeck Machine 1 for the player to build automatically.
