Riftbound Radiance: 4 Errata, New Rules, Riven Leads

Around the release of Radiance (October 23, 2026), the rules and the wording of four cards changed in Riftbound. The new rules apply from October 16, Riot published the four errata on October 9, and in the first events Riven wins 61% of matches (small sample). Radiance boosters now cost from 23 zł in Poland, €4.99 in Germany and $5.50 in the US.

We put it all in one place: the official changes, the first tournament results, and current booster and collection prices in Poland, Germany and the US. The basis is Riot Games announcements, reports from media and the community, and our own offer data, which only adds to that. We covered the release, the Legends and launch-day display prices in the Radiance release article. Cards are a separate matter: on the US platform TCGplayer (prices in USD, US market only), Overnumbered cards have gotten 33–56% cheaper within 11 days of release.

New rules since October 16: three keywords and a separate copy layer

Riot published new Core Rules and Tournament Rules on October 9, 2026, and they took effect on October 16 with the Pre-Rift, a week before release. A lot of it writes down what used to be an unofficial reading.

The set itself brings three new keywords:

• Deploy. Found on gear: it can be played to any battlefield and stays there until it is destroyed or moved.
• Disarm. Found on units: on the first attack in a combat, an enemy unit gets −[M] until the end of the turn.
• Show Off. Found on units and spells: the card checks whether you reveal a matching card from hand or control a matching object on the board.

The biggest technical changes concern resolution order. Copy effects now have their own layer and apply first, and copying itself is a game action. Choices made again, as with Rebuttal and Mystic Reversal, have to be remade in full, and pending items on the chain can no longer be targeted.

There is also vocabulary that prepares the ground for Legacy. "Pick" means a choice without a target, "Choose" means targeting. A unit cannot be attached to anything, so equipment that turns into a unit (Orianna, Lady of Clockwork, for example) detaches. Fixes from the Vendetta FAQ are now part of the rules, including multiple Empower and 2v2 scoring.

The Tournament Rules changes affect everyone who plays events:

1. Deck registration with Neeko. A deck with Neeko, Blending In also registers the Legends chosen for her.
2. Decisions stay. Gameplay decisions can't be changed once the opponent has had to point out information they affect.
3. Bluffing is allowed. Players may bluff about private information.
4. Random deck checks. They happen at the start of a round and cover the whole deck.
5. Loops must be deterministic. No random elements at all.

A second wave follows in January: Riot announces a larger rewrite of the rules together with Legacy. The Radiance Rules FAQ of October 26 takes precedence over the Core Rules until a new document is published. We cover the Legacy release in a separate article.

Four errata: only Neeko really changes deck building

Riot corrected four Radiance cards on October 9, 2026 (Elnuk Herd, Forbidden Technique, Last Caress, Neeko, Blending In), and only two of them change what the card can do. Riot gives one reason for all of them: cards should be easier to understand and describe more clearly how they work.

Data: playriftbound.com, "Radiance Errata Updates" (Oct 9, 2026), riftbound.gg and riftboundfrance.fr as secondary sources, retrieved Nov 3, 2026.

For Last Caress the sources describe the change a little differently. Riot speaks of an editorial adjustment, while the French site riftboundfrance.fr says the clause moved from reminder text into the main text. Nobody claims the effect changes in either version. For Elnuk Herd, the Riot page does not spell out the consequence, so "can buff itself" is our reading of the change, not an official assurance.

Neeko needs a closer look, as she is the most unusual card in the set:

• Deck building. If your deck has at least one Neeko, you choose extra Legends in addition to your starting Legend. They are shared by all Neekos in the deck, must differ from each other and from your Champion Legend, and are registered in the decklist.
• Play effect. When it resolves, you pick one of those Legends and add it to your Legend Zone while Neeko stays on the board.
• Limits. You can't have two copies of the same Legend on the board, so a fourth Neeko adds nothing. If Neeko leaves, the added Legend ceases to exist.
• Nature. These Legends aren't tokens, they enter ready, and your opponent only sees them once they are added to the Legend Zone.

In total, errata currently cover 56 cards: 4 from Radiance, 8 from Vendetta (Jul 23, 2026) and 44 from older sets. Riot's rulings cover 142 questions about 171 cards (riftwatch.gg, Nov 3, 2026). If you buy singles to play, check the current wording first, because old scans and shop descriptions sometimes still show the text from before the erratum.

Two new bans since September 18: Riot weakened Kennen on purpose but did not switch him off

Since September 18, 2026, Ekko Recurrent and Stacked Deck have been banned in Standard and 2v2, which brings the Standard list to 12 banned cards. Riot announced it on September 15, three days before the Los Angeles Regional Qualifier, so that players could still adjust their decks.

Riot's reasoning is specific. Ekko Recurrent powered a Lux combo in which the card grants an extra turn and recycles itself, leaving the opponent almost no window to respond.

Riot stresses that the combo was rare at tournaments but leads to solitaire-style play. Stacked Deck is a cheap, consistent card that was close to a default in Chaos decks and, with Lightning Rush, let Kennen dig through his deck too efficiently.

Data: playriftbound.com ("September Ban List Updates", announced Sep 15, 2026), riftboundfrance.fr (list with dates), riftwatch.gg, retrieved Nov 3, 2026. The reasons for March and July come from community write-ups, not from the announcement cited here.

There has been no new ban since Radiance. The last change to the list was on September 18, and none of the 12 cards has come back. For players that means Kennen and the new Radiance decks run in the same banlist environment.

According to riftbound.gg (report of October 9, events from Sep 26 to Oct 8), Kennen had the best win rate in all of Riftbound in that period, 57%, and won the Showdown Series in Murcia. The September 18 ban falls before that period, so Kennen kept his lead despite the ban.

First Radiance results: Riven leads, but the sample is 110 players

In the first four events with Radiance cards, Riven, The Exile wins 61% of matches, but that is from 13 players at small, mostly online events. The Shonen TCG breakdown (as of October 24, 2026) covers events from October 11 to 23 and 110 players with a known Legend.

Data: Shonen TCG, "Riftbound Radiance Tier List", events Haven Online Challenger Series #5, NovaRiftbound Online Showdown 5, Club9 Riftbound Clash #3 (Oct 11–23, 2026), retrieved Nov 3, 2026.

What the numbers show, and what you should not read into them:

• Riven. 37-24-1 with 13 players and one event win (Club9). But five of nine Riven players at Showdown 5 finished 48th or lower.
• Kennen. Most played (20 players), 48-42-2, 53%. He won Haven, where nobody ran Riven, and did worse at Showdown 5 once many Rivens showed up.
• Yasuo and Kai'Sa. Yasuo 59% (12 players), Kai'Sa 54% (13 players). According to riftbound.gg, Kai'Sa is emerging as the best pick against Riven.
• Akali. 56% with four players, but almost no Radiance cards in those decks, so it is really a Vendetta result.
• Irelia and Rengar. In the riftbound.gg report of October 9 both sat in Vendetta's tier 1, while the Radiance sample has them at 40% and 43% with 4 and 6 players. That is too few players to say they are falling.

A second source paints a different picture: according to RiftDecks (a search-result snippet, we could not open the page itself), Kennen has 15 decks and 13% of the Radiance metagame, Riven 10 decks and 8%. Popularity and strength are different measures and currently point at different Legends.

Tip: don't rebuild your deck around the first tier list. The Shonen TCG author calls it an early read and plans an update after the first big event since release.

Overnumbered cards dropped 33–56% in 11 days on TCGplayer (USD), Signatures hold up better

Overnumbered Riven, The Exile cost $472.14 on release day and $208.06 in our data of November 3, which is 55.9% less. The other top cards fell by a similar amount, only Evelynn lost less at −32.6%.

Data: TCGplayer market prices; Oct 23 TheGamer, Oct 25 tcgcompare.com (as of Oct 26, 2026), Nov 3 CardPulse card data from TCGplayer. The sources' methods may differ, so read the changes as an order of magnitude.

All card prices in this section are TCGplayer prices in USD, i.e. the US market. We did not compare European prices (such as Cardmarket), so the drop may have looked different in Europe.

Evelynn is the exception in the table: on October 25 she sat at $157, today at $200.95, which is 28% above the level three days after release. We don't know why. One possibility is that the October 25 price was a brief low on few sales, but that is only a guess.

The Signature variants (numbers with an asterisk) are much more expensive, but the data is thin. Today Riven Signature costs $1,282.53, Seraphine $1,110.98, Aphelios (Heartsteel) $993.25, Mordekaiser $835.

On release day Mordekaiser was around $1,000 (−16.5%), while Aphelios stands unchanged at $993.25, which says little given how few sales there are. A raw Seraphine Signature reportedly sold for $3,614.20, but that was a single sale and says nothing about the market price.

The Ultimate Rare Packed Amphitheater sits at $551.81 in CardPulse data of Nov 3, about 10% below the roughly $613 of the first days (TCGplayer). For the pull chance and the per-display math, see separate article.

Why are prices falling? We only have a hypothesis, without proof: in the first days people pay for the certainty of getting the card at all, and once opened boosters circulate, supply grows. We will check it on the same cards in two weeks; it is not a forecast.

Update since release: Radiance booster 8–21% cheaper in PL, DE and US

A single Radiance booster now costs 23 zł in Poland, €4.99 in Germany and $5.50 in the US (lowest in-stock offer, Nov 2, 2026). Prices only got this low with the release: in Poland the price fell from 24.99 zł to 23 zł on October 23, in Germany a day later from €5.95 to €4.99. Since the first listings that is −8.0% in Poland (24.99 → 23 zł), −16.7% in Germany (5.99 → 4.99 €) and −20.9% in the US (6.95 → 5.50 USD).

Data: CardPulse, lowest price among offers with status "in stock", EN category, Nov 2, 2026; number of in-stock offers in brackets. For the Pre-Rift kit it is one offer each in Germany and the US, so that is not a market price.

The display divided by 24 gives 22.88 zł in Poland, €5.00 in Germany and $4.79 in the US. The single booster is therefore 0.5% above that in Poland, 0.2% below in Germany and 14.8% above in the US. More on price per booster: Riftbound sealed price comparison.

Showdown Decks cost $19 in the US (tcgcompare: $98 as a preorder price on Sep 28, $17 on Oct 26), 115.99 zł in Poland and €29.95 in Germany. These are separate markets with different shipping costs, which we don't measure.

Against Vendetta (EN), the Radiance booster is 8.0% cheaper in Poland (25 zł → 23 zł) and 7.6% in the US ($5.95 → $5.50).

Display price: in the release article we wrote about a display from 439 zł, because a one-shop preorder offer was visible then. Per CardPulse on Nov 2, 2026 that offer has the status "unavailable", and the cheapest in-stock display costs 549 zł (8 offers). The difference therefore comes from the measure (lowest seen versus lowest available offer) and from the date.

What this means for players, collectors and sealed buyers

For each of the three groups the changes lead to different decisions, but none calls for hurry. The list below carries no investment advice and no price forecasts.

1. Check errata before buying cards to play. Four Radiance cards have new wording, and Neeko allows 1–2 extra Legends instead of exactly three.
2. Put Neeko's Legends on the decklist. The tournament rules have required this since October 16.
3. Don't copy the first tier list. 110 players and four events are not enough to call Riven settled. Wait for the first big event.
4. Buy Overnumbered with the date in mind. They fell 33–56% in the first 11 days. The release-day price is not a benchmark.
5. Compare the price per booster. The display divided by 24 is the yardstick; in the US single boosters are 14.8% more expensive, in PL and DE almost equal.
6. Count collections differently from the display. Showdown Decks and Vault have different contents and can't be compared directly with packs; look at what is inside.

In detail, players should mostly watch errata and rules. Collectors of Overnumbered cards see strong price swings, sealed buyers rather small differences between countries. None of these observations decides future prices: card prices often swing after a release, and our data is from November 3.

Tip: in the Riftbound offers you can set a price alert for a product, and the Radiance guide shows current offers. The set tracker shows your collection progress, and the release calendar the next dates.

What we don't know and what we will check next

Some key numbers in this article rest on small samples or on estimates from the sources. These points stay uncertain.

• Ultimate Rare pull chance. The 0.025% is a tcgcompare estimate and has not been officially confirmed.
• Elnuk Herd. We describe the erratum's effect after the community, not after Riot.
• Meta. The Shonen TCG ranking rests on four small events. It will change after the first big event.
• Card prices. The TCGplayer data comes from different days and methods, and Signatures have very few sales.
• Sealed prices. In some categories it is only 1–2 offers per market, so a single shop can move the price.

Next we will compare Overnumbered and booster prices two weeks after release and see how the meta shifts after the first larger events. Until then, the data in this article is a snapshot of November 3, 2026 and says nothing about a trend.
