How it works
Three steps, all in your browser — free, no account.
Detect
Reads every card's rules text to work out your themes, tribes, and the basics — ramp, draw, removal.
Suggest
Ranks the full catalog by fit to your plan, inside your colors, bracket, and Game Changer budget.
Playtest
Paired solo games on both lists, same shuffles — so the difference is the swap and nothing else.
What it can — and can't — see
These are solo "goldfish" games. They measure speed and consistency, not win rates — no opponents, so removal, politics, and your table's meta don't show up. One-shot treasures and rituals are counted; repeating treasure engines and cast-loop combos aren't, so those benefits look smaller than they play. A card can be right for reasons no simulation can see. Evidence, not a verdict.
