what makes certain pokemon cards valuable are worth? 19 of the Most Valuable

Any images/names/text/mana symbols/set symbols that are licensed, copy written or trademarked by WOTC are not used and any overlapping text or names are pure coincidence

The Meathook Massacre is essentially another Zulaport Cutthroat, a card which (correct me if Im wrong here) is the second most popular black creature of all time

The question current deckbuilding looks to answer is, Which are the best 60 cards? Whenever something is added, something has to be removed

The Trainer card edits followed similarly: I tried to change the sprites and names to generation 2 equivalents, with a special note that Super Energy Removal has been replaced by Master Ball
