Entei from the Pokémon Korean Start Deck 100 set is a promo-style card listed as Unknown rarity (card #55) for the Pokémon Trading Card Game. Collectors view it primarily as a set completion piece rather than a high-value play or investment card, reflected by its current market value of $0.00. Its Korean printing and Start Deck association make it of interest to regional or theme-focused collectors. Sales and grading data, when available, tend to confirm limited demand and low price movement.
