Rare Pokemon cartridge holds a litter of Mews

This special copy of Pokémon Fire Red could make you very, very popular in the GTS or at our own Game Night. That's because it's loaded with Mews. This cartridge was used in one of those Toys 'R' Us Pokémon events, to distribute Mews to store visitors. We don't know exactly how rare something like this is, but there couldn't have been many such cartridges produced for a one-off event at a single retail chain.

We wonder if there would be a noticeable change in the GTS once a bunch of "legit" Mews is unleashed into the trading community. Would the relative barter value of Mews adjust? Oh, man, why is Pokémon economics suddenly so interesting? What is wrong with us?
