Getting Started
A cube is a curated pool of cards used to run a limited-format draft with your friends. Build one here, share it, and draft from it - all in your browser.
1. Browse Cards
Search and filter the full Riftbound card pool. Use the domain chips to filter by color, and the search box for text on the card. On the Cube Editor page you can also use the mini browser on the right panel to add cards without leaving the tab.
2. Cube Editor
Give your cube a name, add cards from the mini browser, and click Save. Use the icon toolbar for Share, Visibility (Public / Private / Draft), Export, Import, Print Proxies, History, Clear, and Delete.
Import / Export: Export dumps your cube as JSON or plain text ("3 Card Name [SET-CODE]") that you can save or paste elsewhere. Import accepts either format back. On import you can pick Add to current cube to merge cards in, or Replace as new cube to start a fresh cube from the paste (rename it and hit Save to make it a new saved cube - your original stays untouched).
Cards you're not sure about can go in the Cards I'm Considering pool. They stay attached to the cube but don't count in stats or draft pools until you promote them.
Click the tag icon on any cube row to add tags like Testing, Might Remove, or Favorite. You can also create your own custom tags.
3. Public Cubes
Browse cubes other players have marked public. Click Copy to Mine to fork one into your own account.
4. Solo Draft
Draft against AI bots from any cube you own or a public cube. Configure pack size, pack count, and bot count; the tool builds packs and runs picks. Send your drafted pool to the Deck Builder when done.
Cube Quick Start: if you own the cube, click "Save draft settings to cube" on the draft config to attach your recommended settings to the cube. Anyone who drafts it later - from your share link or Public Cubes - sees a one-click "Use Cube's Quick Start" button that applies your setup. If you don't own the cube, you can still save your own private settings for it with "Save my settings for this cube".
5. Live Draft
Host a room, share the code, and draft with real players over the internet. Same config controls as Solo. Everyone joins from the Live Draft tab.
6. Draft Deck Builder
Turn a drafted pool into a finished deck. Sort by mana, type, or curve, and export the list.
Tips
- Right panel sections (Cube Controls, Stats, Cube List, Add Cards) can each be collapsed by clicking the header, and resized by dragging the thin divider below them.
- Cube History logs added and removed cards each save so you can see how the cube has evolved.
- Set Visibility to Draft if you want to keep a cube private while you tune it.
Frequently Asked Questions
Do I need an account?
You can browse cards and public cubes signed out. To save your own cubes, run drafts, or share, you'll need to sign in (email, Google, or Discord).
Is this affiliated with Riot Games?
No. This is an unofficial fan project. Riot Games and all associated properties are trademarks of Riot Games, Inc.
How do "Cards I'm Considering" work?
Considering cards are stored with the cube but excluded from stats, legality checks, and draft pools. They're a scratchpad for cards you might add later. Move them into the cube when ready.
Can other people edit my cube?
No. Anyone with your share link can view a cube and copy it, but only you can edit yours.
What's the difference between Public / Private / Draft?
Public: listed on Public Cubes tab. Private: hidden from the tab but viewable via share link. Draft: only you can see it (share links stop working).
Do my "Considering" cards get shared when I share the cube?
They're stored with the cube, but when someone copies it, the considering pool is stripped so they get a clean copy.
How do bots pick cards?
Bots follow a heuristic that considers domain commitment, curve balance, card type mix, and structural bonuses for Legends. Not perfect, but close enough to make solo drafting a useful practice tool.
How do I import a cube from another site?
Copy the decklist and paste it into the Import dialog. It accepts "3 Card Name [SET-CODE]" (our own export) and older "3 Card Name (SET)" formats. Pick Add to current cube to merge in, or Replace as new cube to start fresh - the latter clears the editor but doesn't touch any saved cube until you rename and Save.

Change Log
Newest at top. Build version shows in the footer.
- New Home page: landing hero, quick links to every tool, and the most-loved public cubes. Click the site logo any time to get back to it.
- Browser Back/Forward buttons now work: each tab change (Browse, Cube Editor, Solo Draft, etc.) is a history entry, and #view links survive refresh.
- Public Cubes: love counts now show for signed-out visitors too.
- Public Cubes: clicking "Show description & draft notes" now just expands the notes - it no longer accidentally opens the cube.
- Fixed: with "Set rarity quotas" pack composition, legends and battlefields set to "Random from cube" were being left out of packs. They now mix in by their own rarity as intended.
- Cube drafts: new "Pack composition" option under Card Source. Choose "Random from cube" for the usual random pull, or "Set rarity quotas" to guarantee N Common / Uncommon / Rare / Epic cards in every pack. If a rarity runs out, missing spots fill from the next lower rarity. Works in both Solo and Live drafts.
- Rarity quotas treat alt art, signature, overnumbered, and showcase printings as their base card's rarity so they don't all pile into the Epic slot.
- Cube Quick Start: cube owners can save their recommended draft settings onto the cube (from Solo or Live draft config) so anyone drafting it - including from a share link or Public Cubes - can apply the designer's setup with one click. Copies of the cube keep the Quick Start. Non-owners can save their own private Quick Start per cube that only they see.
- Public Cubes: new "Draft" button jumps straight into Solo Draft with that cube, auto-applying its Quick Start when one is saved. If a solo draft is already running, it asks before abandoning it.
- Fixed: "Copy to Mine" on a shared cube crashed instead of copying.
- Fixed: "(shared)" no longer stacks up in cube names when viewing shared copies of shared cubes.
- Public Cubes: favorite (★) any cube as a personal bookmark and give it a love (❤) that counts toward a shared total.
- Public Cubes: sort by Most loved plus a "My favorites" filter to quickly find cubes you've starred.
- Live Draft: fixed a bug where the phase order was ignored. If you set Legend Mini-Draft (or Battlefield Mini-Draft) before Main, it now actually starts there.
- Card names: champion / legend cards now display as "Name, Subtitle" (e.g. "Ashe, Focused") to match other Riftbound sites, instead of "Name - Subtitle".
- Cube import: choose whether to add cards to the current cube or start a fresh cube from the import. Import now accepts both bracketed "Name [SET-CODE]" (our export) and legacy "Name (SET)" formats round-trip.
- Proxy print: battlefield cards now rotate 90° automatically so they print in the correct landscape orientation on the 3x3 sheet.
- Custom account-wide tags: add your own tags in Settings and they show up in the tag menu on every cube you own.
- Renamed the "Considering" preset tag to "Testing" (with a T icon) so it doesn't get confused with the Cards I'm Considering pool. Existing tags migrate automatically.
- New Help page with usage guide, FAQ, and this change log.
- Right panel sections (Cube Controls, Stats, Cube List, Add Cards) can be collapsed and resized independently.
- Cube History: every save now records which cards were added and removed, with timestamps.
- Card tags: mark cards as Testing, Might Remove, Favorite, or add your own tags.
- Cards I'm Considering: a separate holding area on the Cube Editor for cards you're evaluating. Doesn't count toward the cube or draft pools until promoted.
- Mini card browser on the Cube Editor side panel so you can search and add cards without leaving the tab.
- Cube description / draft notes field for archetype notes and house rules, shown to anyone who views the cube.
- Cube Editor: build and save cubes, set visibility (Public / Private / Draft), share links, import/export, print proxies.
- Public Cubes: browse and copy other players' public cubes.
- Solo Draft: draft against bots from any cube.
- Live Draft: host or join a real-time draft room with other players.
- Draft Deck Builder: turn a drafted pool into a finished deck.
- Sign-in options: email, Google, or Discord.
