This article is about a Japanese Pokémon Trading Card Game card which has not yet been officially released in English and, hence, may not be released outside of Japan. As such, this article may contain translated Japanese terms instead of English terms.
Flip a coin. If heads, put a Curse marker on the Defending Pokémon. When a Pokémon with a Curse marker on it is damaged by an attack by a Pokémon it has Weakness to, that attack’s damage is quadrupled instead of doubled. (The effect is the same if a Pokémon has multiple Curse Markers on it.) (Curse markers stay on the Pokémon as long as it remains in play.)
