Built for Commander

Playtest your Commander deck before game night.

Your commander waits in the command zone, tax is tracked automatically, and you start at 40 life. Find out if the deck actually does the thing before you shuffle up at the table.

Real command zone

Cast your commander from the zone, and the tax climbs by two each time it comes back. No house rules or workarounds.

100-card ready

Paste any decklist and it resolves in seconds. Singleton counts, color identity, and banned cards are checked for you.

Tuned by data

Every session logs mulligans, draws, and land drops so you can see whether your mana base keeps up with your curve. Save Game Replays to walk back through the turns that mattered.

Stop losing to your own mana base.

Deal a hand, goldfish five turns, and know your Commander deck cold before the next pod.
