Which version do you have?
For the cheapest way to own Castform #66, either the 1st Edition or Standard version at $4 is fine. Since both versions are priced the same, there is no immediate premium benefit to choosing one over the other based on edition or scarcity alone. If you just want the card, buy either one. If you are looking for a specific collectible aspect, the current pricing suggests the versions offer no significant advantage to justify paying more.
