Price and rarity shouldnt affect the choice , but I will ask that we keep the choices from a vintage point of view , so WOTC - HG/SS , as the modern cards are just so crazy full art Im thinking a lot would choose from modern lol I would even say Japanese vintage including the trophy / prize cards as those all look so beautiful as well For me : Gold Star Rayquaza Masters Scroll Masters Key Lets see what you choose
That will not be for long though, as the Pokemon TCG Pocket development team confirmed trading will arrive sometime in January
Overall, Korvold is powerful, flexible, and borderline unfair in longer games
Shield Series of thePokmon Trading Card Game
Japanese one came a few years later
The only drawback is that this card cannot use both effects on the same turn, but it is easy to do either during the opponent's turn
