Is gastly the lightest Pokemon card in the world?

Gastly is known for being one of the lightest Pokémon in terms of its in-game weight, but when it comes to Pokémon cards, there may be other cards that are equally or even lighter due to variations in printing and material. The weight of Pokémon cards can vary slightly, but typically, most standard cards weigh around 1.8 grams. Therefore, while Gastly is certainly light, it is not definitively the lightest Pokémon card in the world.
