Elite Trainer Boxes are a great way to get both a variety of Pokémon TCG cards and useful TCG accessories. Each Mega Evolution Elite Trainer Box contains nine Mega Evolution booster packs, a full-art promo card featuring Riolu or Alakazam, 65 card sleeves, 40 Energy cards, damage counter dice, a coin-flip die, a plastic coin, and a sturdy box to store everything. There’s even a player’s guide that provides useful tips for building a deck with cards from the expansion.
