The Pokemon TCG: Scarlet & Violet White Flare Elite Trainer Box includes: 9 Pokemon TCG: Scarlet & Violet White Flare booster packs, 1 full-art foil promo card featuring Tornadus, 65 card sleeves, 45 Pokemon TCG Energy cards, A player's guide to the Scarlet & Violet White Flare expansion, 6 damage-counter dice, 1 competition-legal coin-flip die, 2 plastic condition markers, A collector's box to hold everything, with 4 dividers to keep it organized, and A code card for Pokemon Trading Card Game Live
