Some of the most expensive cards in Pokémon TCG’s Terastal Festival Ex set can be worth hundreds of dollars. These high values often stem from a card’s gameplay value, aesthetic factor and, most importantly, their rarity. Every new main expansion to the Trading Card Game has a list of cards that are highly sought after by both collectors and players, usually because of their increased value in comparison to the rest of the collection. Among the most valuable Pokémon TCG Twilight Masquerade cards is a Special Illustration Rare version of Greninja ex, worth over $300 at the time of writing.
