Guff's Gauntlet
First Warden
Grakk
The gatekeeper of the upper Warren — aggressive, direct, and unforgiving of a slow start.

Guff's Gauntlet
A single-player Commander gauntlet you play with your own deck. The app is your opponent and your bookkeeper — descend the Warren of Embers, outlast its three wardens, and free Commodore Guff.

Play Magic solo — the way you actually want to
Guff's Gauntlet is a solo Magic: The Gathering experience built around Commander. You bring a real deck; the app runs a themed AI opponent and tracks every last point of life, mana, counter, and trigger for both sides — so you can just play.
🎴
Your deck, your call
Import any deck from Scryfall by search or decklist, or pick a Commander and go. The whole card pool of Magic is available.
🧠
The app is the opponent
Each warden is a tuned AI deck that casts, attacks, blocks, and responds on the stack — a real fight, not a solitaire timer.
📖
…and the bookkeeper
Life totals, mana, the stack, counters, tokens, keywords, and zone changes are tracked for both players automatically.
What's inside
A full roguelike descent wrapped around a complete Magic rules toolbox.
🔥
The Warren of Embers
Descend a dungeon of rooms, earn loot and boons between fights, and build your run toward the wardens who guard its dark.
⚔️
Campaign & Sandbox
Run the story campaign with a persistent economy, or drop into Sandbox to spar against any warden on your own terms.
🛠️
Full player toolbox
Bounce, exile, copy, flip, move between zones, add counters and markers, tutor, reanimate, deal direct damage — the manual controls to run any board state.
🃏
Real cards, real keywords
Live Scryfall import plus support for hexproof, shroud, and the keywords that matter — cast your actual cards against the app.

Topple the three wardens
Each guards a deeper reach of the Warren. Beat all three to free Commodore Guff — and learn what the Ember really costs.
Second Warden
Murglax
Deeper in the dark, a grindier threat that punishes greed and rewards a plan.
The Deathless
Vael
Holder of the Ember, forged in deathless fire. He cannot truly be killed — only weathered, and escaped.

Frequently asked questions
Is Guff's Gauntlet free?
Yes — completely. There's no account, no ads, and nothing to buy. Open the app and play.
Do I need to install anything?
No. It runs in any modern browser on phone, tablet, or desktop. If you want, you can "Add to Home Screen" and it installs like a native app that also works offline.
Do I use my own Magic deck?
Yes. You bring your own Commander deck — import it from Scryfall by search or decklist. You play your real cards; the app plays the opposing warden and handles all the bookkeeping.
Is this an official Wizards of the Coast product?
No. Guff's Gauntlet is an independent, unofficial fan project. It is not produced, endorsed, or affiliated with Wizards of the Coast. Magic: The Gathering is a trademark of Wizards of the Coast LLC.
Can I play offline?
Once you've opened it once, yes — the app caches itself and runs without a connection. (Importing new cards from Scryfall needs a connection.)
What platforms does it work on?
Anything with a browser — iPhone, Android, Windows, Mac, Linux. It's a Progressive Web App, so it installs and plays like a native app on all of them.
