The Pokemon card "Ancient Mew" has 30 hit points. The card was given out in 2000 as a promotional item with the purchase of tickets to the theatrical run of the Pokemon movie "The Power of One."
Ancient Mew is a psychic-type, and it can use the move Psyche for 40 hit points' worth of damage. It does not have a resistance but does have a weakness to psychic attacks. Its retreat cost is two colorless cards. These stats were originally displayed via a system of runes. Information on how to decode the runes was given out at events and on the official Pokemon website.
