In each 5-card pack, 4 slots pull from that main card pool, in a variety of rarities, from the normal Super, Ultra, and Secret Rares, to Starlight, Platinum Secret, and the unique Prismatic-style Ultimate & Collectors Rares found only in Rarity Collection sets

Be ready to see Tytannial and Botanical Lion, who are both pretty good beatsticks, and Snowman Eater, who is a pretty decent control card
There are also more Speed Duel cards that can help you customize your favorite Decks: some to flesh out the characters and give a few nods to key moments in Yu-Gi-Oh
None of them really stuck, but Red-Eyes Flare Metal Dragon is great
