Build a Commander deck from what actually wins
Pick a commander and start adding cards. Next to your list sit the staples that raise this commander's win rate in tracked games, the card counts that full decks in your colours really run, and a playtest board. No account needed.
What wins games for Y'shtola, Night's Blessed
The cards that raise this commander's win rate the most in tracked games, compared with decks of the same commander that leave them out. This shelf sits next to every deck in the editor.
Win-rate lift is the lower bound of a 95% interval, so a card has to earn its place. How staples are measured
16 cards printed in the last 90 days already in Y'shtola, Night's Blessed decks, on the New cards tab.
The counts full decks really run
Lands, ramp, draw, removal and six more categories, each measured as the middle half of full Commander decks tracked on Playgroup in your colour identity. In the editor every category is a chip over your list, amber when you are short.
Middle half of 9,606 Five Color decks. Every identity is measured separately.
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. 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.
