Lands 35 to 38
Ramp 12 to 20
Card draw 8 to 14

Middle half of 11,831 Five Color decks. Every identity is measured separately.

Playtest

Goldfish it on a real board

One button in the editor opens your deck on the Playgroup Live board in the browser. Draw, mulligan, play it out alone, or seat a sparring deck across the table and see how the list holds up before you buy a single card.

When the deck is real, track its games with the tracker or on Playgroup Live and its win rate, its arch-enemies and its power read come back into the same page.

What is the Playgroup deck builder?

A free Commander deck builder in the browser, with suggestions that come from tracked games instead of deck-site popularity or generated guesses. For every commander it lists the staples that measurably raise the win rate, sets your card counts against the measured skeleton for your colour identity, surfaces new printings other decks of that commander already run, and opens the deck on a real playtest board.

You can start without an account: the deck lives in your browser as a guest brew until you claim it. Lists paste in from any format, Archidekt and Moxfield decks import by link, and once the deck is built, tracking its games with the tracker or on Playgroup Live feeds its win rate back into the same page.

Deck builder FAQ

Do I need an account to build a deck?
No. Pick a commander or paste a list and the editor opens straight away. The deck lives in your browser as a guest brew. Make a free account later and it becomes yours, with the cards you added still in it.
Where do the staples numbers come from?
From games people track on Playgroup with the tracker and with Playgroup Live, not from how often a card appears on deck sites. For each commander we compare decks that run a card with decks of the same commander that leave it out, and show the lower bound of the win-rate difference. A card has to earn its place on the list.
Can I import a deck from Archidekt or Moxfield?
Yes. Paste the list here, or drop the deck link on the deck template page and it is checked against the measured skeleton first, then opened in the editor. Decks on your account can also stay synced with their Archidekt or Moxfield source.
Can I test the deck before I sleeve it up?
Yes. Every deck with a legal list has a playtest button that opens it on the Playgroup Live board, alone or against a sparring deck, in the browser. No install.
Does it work on a phone?
Building does. Tap a card for its actions, search from the bar at the top, and the suggestions open in a sheet. Playtesting is best on a desktop or a tablet because the board needs the room.
How is this different from a deck site?
A deck site knows what people put in decks. Playgroup also knows what happened when they played them. The staples, the skeleton bands and the deck stats all come from tracked games, so the suggestions are about winning, not about popularity.
Is this an AI deck builder?
No. The suggestions are measured, not generated. An AI deck builder reads card text and predicts what sounds good together; we compare decks that run a card against decks of the same commander that do not, across 202,862 tracked games with a full decklist and a 3 to 5 player pod, and rank on the lower bound of the win-rate difference. Every card on the shelf carries the number behind it, and where there are not enough games to say anything the card does not appear at all.
Can I scan my physical cards into a deck?
Yes, with a free account. Open a deck in the editor on your phone, press Scan, point the camera at a fan of cards and review what it found before adding. Scanning is free while it is in beta.
