How does the Chaos domain play?

Chaos is the purple domain of Riftbound: the League of Legends trading card game. In Riot's deckbuilding primer of 28 July 2025, Chaos stands for unpredictability, rebellion and trickiness. A Chaos card rarely wins by being the biggest thing on the board. It moves units where the opponent does not want them, sends them back to their owner's hand, waits facedown at a battlefield as a Hidden card or comes back from the trash for a second go.

Chaos cards carry a hexagonal symbol with swirls coming out of its center, and Chaos Power comes from the Chaos Rune. Every Legend printed so far has two domains, so Chaos always shares a deck with one of the other five.

What does a Chaos deck try to do?

A Chaos deck tries to win battlefields by outplaying the opponent rather than by overpowering them. Riot's primer says Chaos decks often manipulate position and the trash, use hidden tricks and filter toward the right cards to achieve victory. In the cards, that shows up in four ways: units that move or return to hand, cards played from the trash, Hidden tricks, and effects that dig through the deck for the cards a player needs. The primer gives V from V for Vendetta, Spider-Man and Han Solo as examples of Chaos from popular fiction.

That plan fits a game scored on battlefields. Points come from conquering and holding them, so a defender that is moved away or sent back to hand at the right moment can cost its owner the battlefield just as surely as a defender that dies.

How does Chaos control where units stand?

Chaos moves units, its own and the opponent's, and it sends units back to their owner's hand more than any other domain. More Chaos cards return a unit to its owner's hand than the cards of the other five domains put together, and so far every card that sends an enemy unit back to hand is a Chaos card.

• Gust costs 1 Energy and returns a unit at a battlefield with 3 Might or less to its owner's hand. It is a Reaction, so it can clear a defender out of the way in the middle of a fight.
• Zaunite Bouncer returns another unit at a battlefield to its owner's hand when you play it, whatever that unit's Might.
• Isolate moves an enemy unit from a battlefield to its base, and draws you a card if that leaves an enemy unit alone there.
• Miss Fortune, Buccaneer may be played straight to an open battlefield, one with no units and no controller, and lets your other units do the same. Units are otherwise played to your base or to a battlefield you already control.

Moving works on defense as well. Flash, a Reaction from the Proving Grounds box, moves up to two of your units to your base, out of a fight they would lose.

Why does Chaos have so many Hidden cards?

Hidden suits a domain built on tricks, and Chaos has more cards with Hidden than any other domain. You place a Hidden card facedown at a battlefield you control for one Power of any domain, and from the next turn on you may play it there as a Reaction without paying its cost. Your opponent sees that a card is waiting, but not which one. Hiding a card does not open a Chain, so the opponent cannot answer it, but the card stays only as long as you control its battlefield, which makes the fight for that battlefield the usual moment to play it.

• Teemo, Scout is a 1 Might unit who gives himself +3 Might for the turn when he is played, so he comes out of hiding as a 4 Might defender.
• Tideturner swaps places with a unit you control at another location when you play it, so a hidden Tideturner can bring a bigger unit from your base into a fight.
• Windsinger returns another unit at a battlefield with 3 Might or less to its owner's hand when it is played.

How does Chaos use the trash and the top of its deck?

Chaos treats the trash as a second hand. Many Chaos cards return cards from the trash to your hand or play them straight from there.

• Morbid Return returns a unit from your trash to your hand.
• Soulgorger plays a unit from your trash when you play it, ignoring that unit's Energy cost.
• Fizz, Trickster plays a spell with an Energy cost of 3 or less from your trash, ignoring its Energy cost, and recycles it afterwards.
• Rhasa the Sunderer costs 10 Energy, and 1 less for each card in your trash.

Chaos also fills its trash on purpose. Lunar Boon makes you discard a card and draw two, and Jinx, Rebel readies and gains +1 Might for the turn whenever you discard. Other cards sort the top of the deck: Stacked Deck looks at the top three cards of your Main Deck, puts one into your hand and recycles the other two.

What is Chaos weak at?

Chaos struggles to deal with a threat for good, and Riot's primer says so as well. A unit sent back to hand has to be paid for again and enters play exhausted, so the opponent loses time, but not the card. Few Chaos cards deal damage or kill a unit outright, and the cheap answers have limits: Gust and Windsinger only reach units with 3 Might or less. The lasting answers cost more. Conscription takes control of an enemy unit at a battlefield with 3 Might or less for 5 Energy, and Possession takes control of any enemy unit at a battlefield, but it costs 8 Energy and three Chaos Power.

Chaos also gives its units little that lasts. Ember Monk gets +2 Might for the turn when you play a card from Hidden, and the bonus is gone when the turn ends. The second domain of the deck has to fill both gaps. In Riot's descriptions, Fury brings damage, Body brings strong units that win combats and Order kills units directly, so a Chaos deck often takes its removal or its muscle from its partner.

Which Legends play Chaos?

Chaos has Legends paired with each of the other five domains. Fury and Chaos is tied with Body and Order for the most Legends of any pairing, with six each once the Radiance Legends that Riot has revealed ahead of the set's release on 23 October 2026 are counted. Each pairing leans on a different side of Chaos.

• Loose Cannon, the Legend of Jinx in Fury and Chaos, draws you a card at the start of your Beginning Phase when you hold one card or none, which suits a deck that discards and empties its hand quickly.
• Unforgiven, the Legend of Yasuo in Calm and Chaos, moves a friendly unit to or from its base for 2 Energy and an exhaust.
• Swift Scout, the Legend of Teemo in Mind and Chaos, lets you pay 1 Energy instead of one Power to hide a card.
• Bounty Hunter, the Legend of Miss Fortune in Body and Chaos, exhausts to give a unit Ganking for the turn.
• Heart of the Tempest, the Legend of Kennen in Chaos and Order, is empowered whenever you play a card from anywhere other than your hand, such as from facedown or from the trash.

For a first Chaos deck, Fury and Chaos is the easiest pairing to learn, because Fury's damage covers what Chaos lacks. Several ready-made decks play it: the Origins Champion Deck: Jinx, the Zed deck of the Vendetta Showdown Decks and the Annie deck in the Proving Grounds box. The Unleashed Champion Deck: Vex plays Calm and Chaos instead.

Every Chaos card is in the card list filtered to Chaos, and the Legends page shows every Chaos Legend with the Chaos filter set. Because a Legend sets the second domain of the deck, choosing a Chaos Legend mostly means choosing what Chaos should be paired with, which the guide to picking a Legend takes step by step.
