Esper
Artifact creatures and the new Assimilate mechanic. The Borg Queen gives artifact creatures +2/+2 and assimilates a creature from an opponent's library whenever she enters or attacks.
Phone Play
Phone play works. A larger screen is still recommended.
The landscape phone layout is supported, but card text and controls are easier on a tablet or computer.
Continuing here? Turn your phone sideways when the board opens, then use Fullscreen or Add to Home Screen to make more room.
Solo Playtest
Playtest any Commander (EDH) deck
No account. No setup. Paste a Moxfield or Archidekt link and goldfish in your browser.

Jeskai
Spacecraft and card draw. Jean-Luc Picard, Luminary draws a card when a historic permanent of mana value 3 or more enters, and each second draw in a turn grows a creature and charges a Spacecraft.
Bant
Landfall and exploration. Commander Spock reveals the top card when he enters or attacks and casts it free if its mana value is at most the number of differently named lands you control.
Mardu
Aggressive Klingon Warriors. Worf, Defiant Commander makes a hasty Warrior token, and every attack exiles one card per opponent attacked for you to play.
Echoverse
Four-color (WUBR) polymorph deck. Make tokens with Elspeth, Martial Coup, and Secure the Wastes, then swap them for Darksteel Angel, Archon of Cruelty, or Serra's Emissary from the library with Jace's −3, Mass Polymorph, Synthetic Destiny, and Proteus Staff, while Nissa repeats the trick on landfall.
Dinosaurs
Oversized creatures and trample. Board power cuts Ghalta's cost, so the deck builds a wide green board and then casts a 12/12 for a fraction of its printed price.
New · Sparring
Most playtesters just goldfish. This one fights back.
Turn on Sparring and phantom opponents counter your spells, remove your threats, and cast board wipes, at a cadence measured from thousands of real Commander games. It trains the one skill goldfishing cannot teach: playing around interaction. Import the same Moxfield or Archidekt deck you would test anywhere else, then practice the plays that actually lose games.
How it works
01
Paste a link
Drop in any public Moxfield or Archidekt Commander deck.
02
We import it
Playgroup pulls the cards, resolves prints, and shuffles your library.
03
Goldfish away
Draw, mulligan, cast, move cards between zones, and undo. A solo sandbox, no opponents needed.
An MTG deck tester that counts every card
Use Playgroup as an MTG deck tester before you buy the cards. Import a Commander list, draw sample opening hands, mulligan, and play the first turns to see how the mana and the curve actually feel. Undo any misclick, restart in one click, and turn on Sparring when you want to test the deck against removal and counterspells instead of an empty table.
Frequently asked questions
Do I need an account to playtest a deck?
No. Paste a Moxfield or Archidekt deck link on Playgroup and you drop straight into a solo playtest in your browser. Create a free account later if you want to keep your decks and games.
Which deck sites can I import from?
Moxfield and Archidekt. Paste a public deck link from either and Playgroup imports the cards and shuffles up a fresh game. Plain decklist paste needs a free account for now.
Is solo playtesting free?
Yes. Playtesting any Commander (EDH) deck is completely free, with or without an account.
Does the playtester fight back, or is it just goldfishing?
Both, your choice. By default it is a solo goldfish with no opponents. Turn on Sparring from the board and phantom opponents will counter your spells, remove your threats, and cast board wipes, at a cadence measured from thousands of real Commander games. It trains the one skill goldfishing cannot: playing around interaction.
Can I play multiplayer, not just solo?
Yes, with a free account. Solo playtest is the no-account goldfish mode. Create a free account and you can host or join multiplayer Commander games on Playgroup Live, 2 to 6 players per pod, with voice chat.
What can I do in a solo playtest?
Draw your opening hand, mulligan, cast and move cards between zones, tap, add counters, roll dice, and undo. It is a solo goldfish sandbox, no opponents needed.
Does my playtest deck get saved?
If you playtest without an account, nothing is saved and the session is cleared automatically. Create a free account at any time to keep the deck you imported and the games you played.
Can I use this as an MTG deck tester before buying cards?
Yes. Import the Commander list you are considering, draw sample hands, mulligan, and play out the opening turns to see how the mana base and curve hold up. It is a free MTG deck tester in the browser, no account needed, and Sparring adds phantom opponents when you want to test against interaction rather than goldfish.
Can I share a one-click playtest link?
Yes. Every imported deck has a shareable Playtest on Playgroup.gg link. Anyone who opens it jumps straight into a solo playtest of that deck, no account required.
