Power Creep

A Power Creep is a phenomenon that happens in games that constantly update their content, such as in Trading Card Games like Duel Masters. It is generally when the game gradually unbalances as new content is added, generally when newer cards become stronger and stronger and outshines older cards. (e.g. Quatro Fang, Super Gang Leader outclassing Fighter Dual Fang completely.)

Definitions
In order for a card to be considered a Power Creep, Power and Cost are not the only determining factors as Power is only used to battle other creatures and determining if the creature will be removed by Power-Based Removal. The effects of the Creature must also be taken into account. For example, a Vanilla or Quasi-Vanilla Creature with an overly high cost-to power ratio (e.g. Gonta, the Warrior Savage) is not a power creep,
