How do you share or import a decklist?

A deck for Riftbound: the League of Legends trading card game moves from one player to the next as a list. A deck you saw on a stream or built with a friend reaches you as a link to a deck page or as plain text with one line per card. At the Competitive and Professional levels, a tournament asks for one more list: the decklist you register with the officials before the first round.

What goes into a Riftbound decklist?

A complete decklist names every part of the deck: the Champion Legend, the chosen champion, the Main Deck, the three battlefields and the 12 runes of the Rune Deck. Each card gets one line with the number of copies and the full name of the card, subtitle included. The Tournament Rules ask for "a complete, unambiguous record" of the deck, and the subtitle is what keeps a line unambiguous, because many champions have several units that share the champion's name and differ only in the subtitle.

The Shen Showdown Deck, one of the two decks in the Vendetta Showdown Decks box, shows why. Its Legend is Eye of Twilight, and it holds three different Shen units: Shen, Leader of the Kinkou Order as its chosen champion, with Shen, Kinkou and Shen, Scourge of Shadows in the Main Deck. A line that only says "2 Shen" could mean any of them.

At a Constructed tournament the deck holds exactly one Legend, a Main Deck of 40 cards with the chosen champion among them, 12 runes and 3 battlefields with different names (rule 402.1), and the article on what makes a legal Riftbound deck gives the rules behind each of those numbers.

How do you share a deck from this site?

Save the deck in the deck builder, open its page and press Share. The window shows the link to the deck page with a Copy link button, and on most phones a Send button opens the phone's own share menu. Whoever opens the link sees the Legend, the energy curve and every card of the deck.

A new deck is private, and only you can open its page, even with the link. Tick Make deck public, on the deck page or in the builder, and anyone with the link can see the deck. A public deck that follows every deck rule also appears among the shared decks, where other players find it with filters for each Legend, champion and domain. Anyone can use the builder, but saving a deck takes an account on the site.

Use the Notes field in the builder to say how the deck plays and which cards to keep in an opening hand. The notes show on the deck page and go along with every copy of the deck.

How do you copy a deck as text?

Every deck page has an As text button. It opens the whole list as plain text with a Copy text button, ready to paste into a message or a note. The text starts with the name of the deck and puts each part under its own heading: Legend, Chosen champion, Main deck, Battlefields and Runes. Each line holds the number of copies, the full name and the collector number of the card in brackets. The text of the Shen Showdown Deck begins like this:

Shen Showdown Deck
Legend
1 Eye of Twilight (VEN-147/166)
Chosen champion
1 Shen, Leader of the Kinkou Order (VEN-138/166)
Main deck (39)
2 Charm (OGN-043/298)

The chosen champion has a heading of its own, so the Main deck heading counts 39 cards in a deck of 40. The code in brackets is the collector number printed on the card: the set, the place of the card in the set and the size of the set, and the article on card numbers explains each part.

How do you bring someone else's deck into the builder?

Open the deck's page and press Create copy. The deck builder opens with the cards, the name and the notes of that deck, and once you save it, it is a new private deck of your own that you can change as you like. The original stays as it was. Every deck that is not your own has the button, the ready-made decks included: switch the shared decks to Sold in a box to find the Champion Decks, the four Proving Grounds decks and the Showdown Decks as they come out of the box. A copy of a Champion Deck is a good start for the changes described in how to upgrade a Champion Deck.

A list from somewhere else, such as a text a friend sent you, goes in by hand. The builder takes the cards one at a time: pick the Legend first, then the chosen champion, then search for each card by name and add as many copies as the list says. The builder only offers cards that fit the Legend's domains, and it lists whatever still keeps the deck from being legal.

How do you hand in a decklist at a tournament?

At a Constructed tournament played at the Competitive or Professional level, every player registers a decklist before the first round. A Summoner Skirmish is played at the Competitive level, so it asks for one. At casual events such as Nexus Night, the head judge may ask for decklists, and even without them players are expected to keep the same deck all event unless the organizer allows a change.

The registered list records the Legend, the battlefields, the Main Deck with the chosen champion, the Rune Deck and the sideboard, where the format allows one. From 16 October 2026, when Riot's October 2026 update of the Tournament Rules takes effect, the list also names the Legends chosen for Neeko, Blending In. Neeko is a champion unit of Radiance, with its release on 23 October 2026, and a deck that holds it chooses up to three more Legends while it is built. Once the list is handed to an official it cannot change. A list that breaks the deck rules, or a deck that does not match its list, is a Decklist Error: the player loses a game and the list is corrected. At Competitive and Professional events, judges should check at least one deck in ten, chosen at random.

The builder on this site has no place for a sideboard, so write the sideboard of up to 10 cards under the copied text yourself, keeping to three copies of a card across the Main Deck and the sideboard together. Ask the store how and by when it wants the list. Riot announced on 4 September 2026 that playriftbound.com would become the home of Riftbound organized play from 14 September 2026, and it listed easier decklist creation and validation across competitive formats among the things it is working on next, without a date.

Will your opponent see your decklist?

Usually not. The Tournament Rules normally treat every player's decklist as private information. The head judge may run an event, or only its final rounds, with open decklists, and then each player gets the opponent's decklist to read at the start of every match and between games, but never during a game. The Tournament Rules say that Professional events should typically be run with open decklists, although the head judge decides at every level.

The shared decks are the place to find a list to copy, and the deck builder checks your own as you build it. A copied list is still untested, and playing it against other decks shows which cards to change, as the article on how to test and improve a deck works through. What an event asks beyond the list, from sleeves to penalties, is in the article on the rules of a tournament, and the article on sideboards covers swapping cards between games.
