Solo playtest

Playtest a Commander deck online

Paste a Moxfield link or a decklist, and your deck is dealt onto a full Commander table in a few seconds: three bot seats take their turns, but they are dealt no cards, so the table is a goldfish. It runs in the browser, it is free, and it needs no account: nothing you import is saved.

How it works

Import. The URL of a public Moxfield deck, or a list pasted as text, one card per line (1 Sol Ring). When the list does not say which card is the commander, you pick it among the candidates.
Deal. Your commander goes to the command zone, your library is shuffled and you draw seven. Take a mulligan as often as you need.
Play. Draw, play lands and spells, tap and untap, attack, put counters on permanents, scry, create tokens, and move any card between library, hand, battlefield, graveyard, exile and the command zone.
End your turn. Bot Alpha, Bot Beta and Bot Gamma then take theirs, but they are dealt no cards, so a bot's turn passes without a land, a spell or an attack. Restart deals the same list again.

What it is for

Goldfishing, with a little pressure: how often the deck has its mana by turn three, whether the curve casts the commander on time, what a typical opening hand looks like, how long it survives a table that hits back. The solo playtester runs on a small engine of its own and you move the cards yourself, the way you would at a kitchen table — it does not enforce every rule. A second playtester, built on the open-source Forge rules engine, is described in How Lotus Vault works. For step-by-step tips, read the playtest guide.
