What does the matchup estimate mean?

It is the model’s estimate for a decisive match between the selected complete decks under its supported rules and inputs. It is not a guarantee for a particular battle or a rating of either player. Card levels, tower troops, rare combinations, balance changes, and individual decisions can affect what happens in game.

How should I use it?

Use the estimate to compare deck ideas and spot potential matchup strengths. The model cannot see starting hands, placements, timing, or player skill. For how estimates and support are handled, read the model methodology, or use the counter deck finder to explore candidate decks against a target.
