Domains explained
The six domains plus Colorless — what each one plays like, how dual cards work, and why the pairings are not random.
A card’s domain decides which decks it can go in. There are six, plus Colorless for cards that belong anywhere. Knowing what each one is trying to do makes card evaluation much faster.
Body
Big, durable units that expect to win a fair fight. Body wants the board to stay on the board, and it rewards committing to it.
Calm
Defensive tools, careful resource use and answers held up. Calm is happy for the game to go long, because it gets better the longer it goes.
Chaos
Effects that break the expected shape of a turn. Chaos trades consistency for reach, and punishes opponents who plan too precisely.
Fury
Damage early and often. Fury is trying to end things before the opposing deck comes online, and its cards are priced for the early turns.
Mind
Drawing, digging and steering. Mind spends its early turns setting up and expects to out-resource the opponent later.
Order
Buffs, coordination and boards that get stronger together. Order rewards building a plan and sticking to it.
Colorless
No domain requirement, so it slots into any deck. Colorless cards are the connective tissue of the format rather than its identity.
Dual-domain cards
Some cards carry two domains and belong to both. They are more flexible in deckbuilding but narrower in what can play them, since a deck has to accommodate both identities. Roughly a sixth of the catalog is dual.
The pairings are not random. Thematically adjacent domains share a lot of cards; opposed ones barely share any. You can see the exact counts on each domain page — the pattern holds consistently, and it tells you which two-domain decks the game is actually built to support.
Colorless is a different thing
Colorless cards have no domain requirement, so any deck can play them. That sounds like it should make them valuable, and it does not: they are the cheapest group in the catalog by a wide margin. They are utility pieces, printed at common and uncommon, and there is little scarcity to price.
Does domain affect price?
Barely, and not in the way people expect. The average price per domain sits in a narrow band, because what makes a card expensive — being a signature or alt-art printing of a popular champion — cuts across every domain equally. A domain looks expensive when it happens to contain a popular champion’s chase cards, not because of the domain itself.
