Riftbound Unleashed Set 3 Hits Stores Worldwide Today With New Mechanics, Champions, and a Single Ultimate Rare Baron Nashor

The third set in Riot Games' League of Legends trading card game arrives in English-speaking markets today, May 8, 2026. Riftbound: Unleashed brings more than 220 new cards, three new mechanics, a fresh batch of champion legends, and a brand-new top-shelf rarity tier that is already drawing the kind of attention usually reserved for chase Pokemon and Magic cards.

What is in the box

Unleashed is built around the idea of hidden strength and patient power, and the new champion roster fits that theme. Returning faces include Master Yi, Diana, Vi, and Pyke, and Riot is folding in a few champions making their TCG debuts, including Kha'Zix, Lillia, and Ivern. Worldwide product hits shelves in three forms today: booster packs, the new Vault product, and the standard pre-constructed legend decks tied to specific champions.

The Vault is the headline-grabber for collectors. It ships in a reusable card-storage box and contains six Riftbound: Unleashed booster packs, three double-sided full-art tokens, two dividers, and a stack of 36 basic runes. It is positioned as a midweight collector product, sitting between a single booster and a full booster box, and pre-orders moved quickly in the days leading up to launch.

Three new mechanics to learn

Unleashed introduces three brand-new keywords that change how Riftbound is played:

• Ambush — lets you play certain cards as a reaction on a battlefield where you already have units, opening up the kind of bluff-and-respond plays Magic and Lorcana players know well.
• XP — a new resource that builds up over the course of a game and gets spent for unique advantages, rewarding players who can hold a position rather than burning everything in one turn.
• Hunt — cards with the Hunt keyword earn XP whenever they are used to conquer or hold a battlefield, tying the new resource directly to aggressive board play.

The Baron Nashor chase

The set's biggest collector hook is a new top-tier rarity called Ultimate Rare. According to Riot, Ultimate Rare cards appear in less than one percent of packs, and Unleashed has exactly one of them: Baron Nashor.

One Ultimate Rare in the entire set, pulled at less than 1 in 100 packs. That math is going to drive single-card prices the second the first copies hit the secondary market.

Expect Baron Nashor's first eBay and TCGplayer listings to climb fast in the next 48 hours. Sealed Vault prices will likely move with them.

What this means for shops and collectors

Riftbound is still the new game in the room, but Unleashed is the first set where Riot has clearly designed for collector behavior on top of competitive play. The combination of a single high-pull Ultimate Rare, a Vault product designed to be displayed, and 30-plus alternate art cards is the same template Pokemon and One Piece TCG have used to drive secondary market activity. If you have a local game store running Riftbound events, today is a date to circle.
