# Riftbound Rules Explained — Every Mechanic, In One Place

_2026-07-31 · RiftCompare_

A hub for how Riftbound actually works: the keywords introduced in Vendetta, the chase-print numbering, deck construction, the banlist, and the event formats — each linked to a full guide.

Riftbound's rules questions cluster around a handful of things: the newer keywords, what the odd collector numbers mean, how decks are legally built, and what's currently banned. This page is the index — each section links to the full guide rather than repeating it here.

> **On sourcing:** we only publish rules explanations where we can point at Riot's own rules text or official reveal coverage. Where a keyword is printed on cards but hasn't been documented officially in a form we can cite, we list the name without inventing what it does. That's why this hub covers some keywords in depth and simply names others.

## The Vendetta keywords

Vendetta introduced three mechanics, and they generate the bulk of current rules searches:

- **[Empower explained](/guides/riftbound-empower-explained)** — upgrading a card that's already in play by paying an extra cost later. Also see the worked example in **[Jayce & Mel: Empower in practice](/guides/jayce-mel-riftbound-empower-explained)**.
- **[Flow explained](/guides/riftbound-flow-explained)** — playing cards straight from your trash, turning discarded cards into a second pool of plays.
- **[Burn explained](/guides/riftbound-burn-explained)** — sending cards to the trash, either your own to fuel Flow-style payoffs, or an opponent's as a deck attack.

All three together, with how they interact: **[Vendetta's new mechanics](/blog/riftbound-vendetta-new-mechanics-flow-burn-empower)**.

## New card concepts

- **[Unit-Gear and Decrees](/blog/riftbound-vendetta-unit-gear-decrees)** — two card concepts Vendetta introduced.
- **[Overnumbers explained](/guides/riftbound-vendetta-overnumbers-explained)** — what a collector number beyond the set total means, and how signed and Overnumbered prints differ.
- **[Understanding card rarity](/guides/understanding-riftbound-card-rarity)** — the rarity tiers, and where Showcase and alt-art printings sit.

## Deckbuilding rules

- **[How a Riftbound deck is built](/guides/how-a-riftbound-deck-is-built)** — deck construction, Legends, and how the pieces fit together.
- **[Building for Vendetta](/guides/building-for-riftbound-vendetta)** — deckbuilding with the new set's cards and domain pairings.
- **[Vendetta synergies with existing cards](/blog/riftbound-vendetta-synergies-with-existing-cards)** — how new cards interact with earlier sets.

## What's currently legal

- **[The banlist explained](/guides/riftbound-banlist-explained)** — how bans work and what they mean for your decks.
- **[The July 2026 ban list update](/blog/riftbound-july-2026-ban-list-update)** — the most recent changes.

Bans and errata move prices as well as decks — **[why Riftbound prices change](/guides/why-riftbound-card-prices-change)** covers that side.

## Event formats

- **[Pre-Rift rules explained](/guides/riftbound-pre-rift-rules-explained)** — how Riftbound's launch-event format works.

## Keyword reference

Individual keyword pages, each with the real cards that use it, live under **[/keywords](/keywords)**. Cards themselves are searchable in the **[card database](/browse)**, and every card page shows its full rules text alongside live prices.

## Riftbound rules FAQ

**What is Empower in Riftbound?** Empower gives a card the potential to gain new abilities once it's already in play, usually by paying an extra cost on a later turn — a cheap play now, a bigger payoff later. Full detail in the Empower guide.

**What is Flow in Riftbound?** Flow is a Vendetta keyword that lets you play a card straight from your trash instead of your hand, so discarded and used cards become a second pool of plays rather than being gone for good.

**What is Burn in Riftbound?** Burn sends cards from a Main Deck to the trash — either your own, to fuel Flow and other trash payoffs, or your opponent's as a deck attack.

**What does Overnumbered mean on a Riftbound card?** It's a collector number that runs past the set's stated total — for example a number higher than the set size — marking a chase printing that sits outside the main numbered run. The Overnumbers guide covers how these differ from signed prints.

**Where can I find Riftbound's current banned cards?** The banlist guide explains how bans work, and the July 2026 update covers the most recent changes.
