Like most Pokmon cards, the value of Banette depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Crystal Guardians)
Later on, it would also eventually be helpful to have people willing to help build decks for NPCs to use, as well as contributing ideas for dialogue and side-quests
In my opinion, Drakrai is a strong Pokmon and has a ton of potential but unless grass decreases its use or there is a way to pair it up with strong one-prizers, I dont really see Darkrai making a short-term impact
There is still some question as to if the items were authentic, and the original post has been deleted
