Delta Species · #94
Holon Research Tower is a Trainer card from the Delta Species expansion of the Pokémon Trading Card Game (card #94, Uncommon).
This card stays in play when you play it. Discard this card if another Stadium card comes into play. If another card with the same name is in play, you can't play this card.
Each player's basic Energy cards attached to Pokémon that has δ on its card are both their usual Energy type and Metal type but provide only 1 Energy at a time. (Has no effect other than providing Energy.)
