Solo playtesting, done right
Goldfish faster than you can sleeve up.
No opponent needed. Deal hand after hand, run your first five turns, and redeal the exact same opener to try a different line. Undo rewinds any mistake, and any game can be saved as a Replay to watch back turn by turn.
Free forever. Import and export decks anytime, so you are never locked in.

Mulligan like the pros
Full London mulligan support: draw a fresh seven, bottom the extras, and track how often your hands are keepable.

Redeal the same hand
Keep an interesting opener and replay it against a reshuffled library to compare lines, not luck.

Stats that add up
Mulligans, draws, and lands by turn three are logged automatically across sessions, turning gut feel into numbers.
A hundred hands before Friday night.
The fastest way to learn your deck is to goldfish it. Start dealing in seconds.
