What are colorless or neutral cards?

Most cards in Riftbound: the League of Legends trading card game belong to one or two of the six domains: Fury, Calm, Mind, Body, Chaos and Order. Each domain has a color of its own, and a deck may only play the domains of its Legend. A small group of cards belongs to no domain at all. These cards are called colorless, and no deck is closed to them.

Riot uses more than one name for them. Riot's card gallery lists their domain as Colorless, the reminder text on Neeko, Blending In speaks of Neutral cards, and the Core Rules describe a card with no domain and call the tokens domainless. All of these mean the same thing.

Which cards are colorless?

Three kinds of card are colorless so far: battlefields, tokens and a single champion unit.

• Battlefields. Every battlefield printed so far is colorless, from Targon's Peak in Origins to Firelights' Hideout in Radiance, the fifth set, with its release on 23 October 2026. The Core Rules leave room for a battlefield with a domain, but Riot has not printed one.
• Tokens. The Core Rules state that tokens have no domain, so a Sprite, a Recruit or a piece of Gold is colorless, whichever card made it. A token can only take on a domain from another effect, as a Reflection does when it becomes a copy of a unit.
• A champion unit. Neeko, Blending In from Radiance is the first colorless card for the main deck. She is an Epic champion unit, numbered 167/167 as the last card of the set.

So far no Legend, rune, spell or signature card is colorless, and neither is any other unit or gear card of the main deck. Every Legend has two domains, each of the six basic runes belongs to the domain it is named after, and every spell and every gear of the main deck has at least one domain.

How can you tell that a card is colorless?

A colorless card shows no domain color. A unit, spell or gear of a domain carries the domain symbol in its lower right corner and a name band in the domain's color. Battlefields and tokens are printed in gray and have no domain symbol at all. Neeko, Blending In has a silver name band, and the corner where a domain symbol would be holds a plain gray ring.

The card number gives a hint as well, since the numbered colorless cards come last in every main set. In Radiance, Neeko, Blending In follows the battlefields.

Which decks can play a colorless card?

Every deck can. Rule 103.2.b.5 of the Core Rules says that a card with no domain is permitted in decks of any Domain Identity, which is the set of domains a deck takes from its Legend. Loose Cannon, the Legend of Jinx, is Fury and Chaos, and Nine-Tailed Fox, the Legend of Ahri, is Calm and Mind. The two decks share no domain, yet both can bring Targon's Peak as a battlefield and both can play Neeko, Blending In.

A colorless card does not widen a deck's domains. The Jinx deck still plays only Fury cards, Chaos cards and colorless cards, and its 12 runes are still Fury Runes and Chaos Runes, because every rune has to match the Legend's domains and no rune is colorless. The usual limits stay in place too: a deck may hold up to three copies of Neeko, Blending In, as of any card with the same name, and its three battlefields must all have different names.

How do you pay for a colorless card?

Most colorless cards are never paid for. Battlefields are in play from the start of the game and are never played, and tokens are created by other cards and have no cost. Neeko, Blending In is the exception: she costs 6 Energy and one Power.

A Power symbol in a card's cost normally asks for Power of the card's own domain. On a card with no domain, rule 135.2.e.6.b of the Core Rules turns it into Power of any domain, so any rune you recycle can pay for the Power cost of Neeko, Blending In, whatever the domains of your deck. Energy has no domain either, so any rune you exhaust can pay her 6 Energy.

The same holds for Accelerate. When a unit with no domain has Accelerate, rule 805.1.b.2 lets you pay the Power part of that extra cost with Power of any domain. When you conquer Firelights' Hideout, the next unit you play that turn has Accelerate. If that unit is Neeko, Blending In, she can enter ready for 1 more Energy and one Power of any domain.

What makes Neeko, Blending In different?

The ability of Neeko, Blending In starts before the game does. When a deck holds her, you choose up to three other Legends while you build it, each with a different name from the others and from your own Legend. When you play her, you add one of those Legends to your Legend Zone, and it stays there for as long as she stays on the board. For that time the deck has a second Legend at work.

Riot changed the text of the card with its errata of 9 October 2026, two weeks before the release of Radiance, as Riot's announcement says: the printed card asks for exactly three Legends, and the new text lets a deck choose fewer. At events where decks are registered, the Legends chosen for Neeko, Blending In go on the decklist and cannot be changed once it is handed in, as rule 401.2.a of the Tournament Rules says. No Legend has the champion tag Neeko so far, so in Constructed Neeko, Blending In fits any deck but cannot be its chosen champion, because rule 103.3.a.2 of the Core Rules asks for a champion unit with the tag of the deck's Legend.

Should you put colorless cards in your deck?

For battlefields the question never comes up, because every deck needs three and all of them are colorless. Choose them for your plan: a deck full of gear gets more out of Ornn's Forge, which makes the first non-token gear you play each turn cost 1 Energy less while you control it, than a deck of spells does.

Neeko, Blending In is a real choice. She costs 6 Energy for 4 Might, so she arrives late in a game, and most of her worth lies in the Legend she brings along. She suits a deck that expects to reach its late turns and has a clear use for a second Legend's ability, more than a fast deck that wants to win early.

The battlefields page lists the battlefields of every set and the tokens page shows the printed tokens. The deck builder lets colorless cards into every deck. Because a colorless card adds no domain of its own, what it does for a deck depends on the cards around it, and each of the six domains plays differently. Neeko, Blending In is printed at Epic, a gem that says how often a card turns up, and the article on which rarities Riftbound cards come in explains the other gems.
