Negative effects are card effects that are detrimental to the user or controller of those cards. Negative effects may most often be found in over-powered Monster cards that have a higher ATK for their Level than would normally be found, such as in "Infernal Incinerator," "Ultimate Obedient Fiend," or most Level 4 or lower monsters with greater than 2000 ATK. They may range from damaging the controller's Life Points to making themselves unable to attack. Others do not harm the user directly but give the opponent an advantage, such as allowing the opponent to draw extra cards or increasing the opponent's Life Points.
