Neo Genesis is a set in the Neo series. It was released on December 16, 2000. The printed size is 111, and the checklist is the same length. Metal Energy is 19/111, in position 19 of 111 on this checklist. Before it is 18 Typhlosion, and after it is 20 Cleffa. The listed rarity is Rare Holo.
Metal Energy is an Energy card. It is listed as Special.
Milky Isobe illustrated this card. The same name is on 22 other cards in the catalog.
The card text says: Damage done to the Pokémon Metal Energy is attached to is reduced by 10 (after applying Weakness and Resistance). If the Pokémon Metal Energy is attached to isn't Metal, whenever it damages a Pokémon, reduce that damage by 10 (before applying Weakness and Resistance). Metal Energy provides Metal Energy. (Doesn't count as a basic Energy card.)
I keep a set binder for Neo Genesis, meant to hold every card of that set. This card is one slot in the Neo Genesis set binder. I still need this card.
