There’s a saying in trading card game communities: Reading the card explains the card. The same can be said of Disney Lorcana, the media giant’s newest venture into the world of TCGs — especially considering that the game’s developer, Ravensburger, hasn’t released the official rules yet. The game won’t be available until 2023.

But during its D23 Expo, Disney did show off seven new cards from the game,offering a first look into the characters, card templating, and art style of Lorcana. With a keen eye — and some experience with other TCGs, like Magic: The Gathering, Hearthstone, and even Gwent — you can see the telltale fingerprints of existing designs and popular mechanics.Elsewhere, lingering questions remain that will require official confirmation from the game’s designers.

Based on the visible elements shared across cards, including the consistent features and the subtle card-by-card differences, we can make some educated guesses based on proven game design mechanics that Lorcana’sarchitects were likely influenced by.

In the top left corner of every character card is a prominent number that feels similar to what other card games usually refer to as casting cost. On Stitch, that number is 6, and on Captain Hook it’s 1. Maleficent is 9, and so on.

And, though it remains to be seen what kind of resources players will use to pay this cost, there’s a noteworthy quality that all the numbers share across the revealed cards — the resource system appears to be universal.

Universal resources are surprisingly uncommon in top-tier TCGs. In Magic: The Gathering, players leverage a resource known as “mana” that corresponds to the cards
