What Grimoire of the Planes does, how to get started, and every page in it, in one place.
Grimoire of the Planes is a deck-building and collection companion for Magic: The Gathering — build and validate decks across every format, track the cards you own, and discover the combos hiding in your collection. It's free to get started.
Getting started
- 1
Register and verify your email — check spam once if it doesn't show up right away.
- 2
Add some cards to your Arcanum. Search and add them one at a time, or bulk-import a CSV — an MTG Arena export works directly.
- 3
Build a deck in the Studio: pick a format, add cards, and mark your commander if the format uses one.
- 4
Open the Combos panel inside your deck and hit Random Combo, or search by color and format to see what's hiding in your card pool.
- 5
Want more? Apprentice and Alchemist unlock even more, including Chronicler, the AI deck assistant — see what each tier offers below.

Your Arcanum
A searchable inventory of the cards you own, backed by Scryfall's full card database. Add cards by search, bulk-import a CSV, or scan them with your phone's camera.
- Search and add by name, or bulk-import a CSV — an MTG Arena export works directly
- Scan physical cards with your phone's camera
- Owned copies and wishlist copies are tracked separately
- Try a small collection right in your browser, no account needed
Decks
Every deck you're building, grouped by format, with card art on every tile. Start from scratch, upload an existing decklist, or build from an official precon.
- Upload a decklist, or paste one in
- Start from an official precon instead of a blank deck
- Each tile shows its format and card count at a glance
The Deck Builder Studio
Pick a format and every deck-size, singleton, and copy-limit rule is enforced live as you build, with banned and not-legal warnings and a one-click cleanup if a commander's color identity gets crossed.
- A commander pick locks color identity, with a one-click cleanup for anything outside it
- Land helpers fill in a sensible basic count, or re-split your mana base to match your color pips
- Export straight to MTG Arena's import format
- Combo Web lays out your whole deck's known combos as one interactive map, showing how the pieces connect
- Chronicler, the AI deck assistant, lives in the Combos panel — an Alchemist-tier perk (see below)
The Grimoire
A searchable mirror of Commander Spellbook's entire combo database, open to everyone, no account needed. Search by color identity, format, or a specific card, and add anything you find straight to a deck.
- 100,000+ known combos, mirrored locally for instant search
- Filter by color, format, card, or how many pieces the combo has
- Every combo gets its own explanation of why it works, written the moment you open it
- Combo Web turns any card into an interactive map of every combo it's part of
- Pieces you don't already own go straight to your wishlist
Chronicles
Decklists from Magic tournaments, not a hypothetical meta guide. Search by format, card, or tournament to see what people are playing and winning with.
- 180,000+ tracked tournament decks
- Search by format, card, or a specific tournament
- Every deck gets an archetype tag, the same classifier your own decks get
The Codex
Win-rate stats computed from tracked tournament results — by archetype, by color identity, or both at once. Facts only: low-sample cells are marked, never guessed at.
- Win rate by archetype and by color identity
- A matchup heatmap with a legend explaining the scale
- Cards that overperform or underperform their archetype
Membership tiers

Where the data comes from
- Scryfall — the card database this app is built on: card text, images, and format legality for every printing.
- TopDeck.gg — official tournament results, the source behind Chronicles and the Codex.
- Commander Spellbook — the known-combo database mirrored into the Grimoire.
Works on your phone too — the Quick Start life counter has its own full-screen mode built for exactly that. Your collection and decks are private to your account; see the privacy policy for details.
Every page in the app has its own "?" near the top — click it for a quick, on-page walkthrough of exactly what you're looking at.
