Here's why:
* Mew is not ancient: Mew is a mythical Pokémon, not an ancient one. While it's often depicted as a small, cat-like creature, it doesn't have any ties to an ancient lineage in the Pokémon world.
* No official "ancient" variants: There are different versions of Mew cards, such as different rarities (common, uncommon, rare, etc.), different artwork, and different sets. However, there is no official card with the name "Ancient Mew" or a similar concept.
If you're looking for a particular Mew card, try searching for it online or at your local card shop. You can specify the set, rarity, or artwork to find what you're looking for.
Be aware of scams: Beware of websites or sellers claiming to have "ancient" or "limited edition" cards for sale, especially if they're asking for an unreasonable price. These may be fake or counterfeit cards.
