Quick answer
CardSpicy takes a deck’s identity from the Legend rather than from the cards in it, because Riftbound works the other way round: you choose the leader, and it chooses your colours. The six domains — Fury (red), Order (yellow), Body (orange), Mind (blue), Chaos (purple) and Calm (green) — are identity rather than flavour, and every card in the deck has to fit the domains its Champion Legend carries. In the first set each Legend has two domains, so a deck is always some pair drawn from the six.
Building a Riftbound deck starts with the Legend rather than with a list of cards, because until the Legend is chosen you do not know what is legal to include.
Riftbound divides its card pool into six domains. They behave the way colours behave in other card games — they are identity rather than flavour — but the game does something unusual with them. You do not choose your colours and then choose a card to lead the deck. You choose the leader, and it chooses for you.
| Domain | Colour | What it is for |
|---|---|---|
| Fury | Red | Damage, and burning the opponent down |
| Order | Yellow | Removal, and value from your own units dying |
| Body | Orange | The biggest units on the board |
| Mind | Blue | Card draw and equipment |
| Chaos | Purple | Movement, and recovering cards from the trash |
| Calm | Green | Defence and board control |
The Legend decides, not you
Your Champion Legend defines your deck’s domain identity, and every card in the deck has to fit it. A card showing one domain needs that domain on your Legend; a card showing more than one needs all of its domains covered. Building a deck therefore starts with the Legend rather than with a list of cards, because until the Legend is chosen you do not know what is legal to include.
In the game’s first set, all Legends have two domains to build around, which means a deck is always some pair drawn from the six.
The Legend is also the strategy
The Legend stays in play from the start of the game and it brings its chosen champion with it. Legend and champion between them decide what the deck is trying to do: quick strikes, an accumulating army, or one powerful and mobile fighter. The domains then decide which of those plans is actually available.
The runes come from the same identity
Costs are paid with runes, which come from a separate rune deck rather than from the main deck. That rune deck is also restricted to the deck’s domain identity. Each turn you gain two new runes, and they can be used in two ways: turned sideways and used up temporarily to pay ordinary costs, or spent outright and returned to the rune deck to pay for more powerful cards. The runes cycle back as the game goes on.
Why this matters to a collector
Domain identity is the reason the same card can be central to one deck and unusable in another. It also explains why the Legend is the card a deck is built around rather than one card among many: without it there is no deck. The Riftbound card index lists the card types each domain draws from.
What this page does not claim
No prices, and no card counts. The six domains and the way a Legend fixes identity are taken from the publisher’s own rules and product pages; where Riot does not publish a detail, this page leaves it out.
Frequently asked questions
What are the six domains in Riftbound?
Fury, Order, Body, Mind, Chaos and Calm. Each is also referred to by a colour, and each is built around a different way of playing.
How many domains can a deck use?
Your Champion Legend defines the deck’s domain identity. In the game’s first set, all Legends have two domains to build around.
Can I put any card I own into my deck?
No. Domain identity is strict: a card showing one domain needs that domain on your Legend, and a card showing more than one needs all of its domains covered.
Are domains the same as colours?
They do the same job colours do elsewhere: they are the identity that decides what a deck may contain. Each domain is also referred to by a colour name.
What is a Champion Legend?
The card a Riftbound deck is built around. It stays in play from the start of the game, it brings the chosen champion with it, and it defines the domains the deck may use.
