Three currents.
One engine.

Your recorded encounters form Mira’s sea chart. Each slice shows an opponent’s share after the recency settings are applied. A large slice has more weight in every deck’s overall score. Hover a slice to inspect that exact matchup’s Global, Trust and Personal voting populations, evidence origins and health.

Cogwick supplies an opinion and health for each archetype-versus-archetype matchup. Mira multiplies each opinion by that opponent’s wheel share and adds the results. The deck with the best estimate across the whole field leads the list. Select a deck to inspect its matchups and missing cards.

An advantage of +3 percentage points means an estimated 53% win rate against this field, compared with an even 50%. It is an estimate, not a forecast for your next match.

Thresholds with no recommendable deck are disabled. If the evidence changes, an unavailable selection returns to the highest available threshold. Health is averaged over your whole opponent wheel before this filter.

Mira averages matchup health using the same opponent shares as the wheel. Opponents below 3% form Other. If their combined share is below 3%, that small group is left out of the wheel and weighting; the remaining shares total 100%. Other contributes when its combined share is at least 3%. Risk is 100% minus average health; it is not your chance of losing.

This sets the minimum evidence health a recommendation needs across the whole wheel. At 60, Mira excludes decks below 60% field health. The threshold never changes their matchup opinions. A stricter limit can leave no available route.

Adaptiv gives newer encounters more influence, Balanced takes a middle course, and Conservative keeps a steadier memory. Phi weights Personal and available Observer counts in the same 30-minute intervals, remembering only the last seven days across patches. Weight halves after 3 hours, 24 hours or 3 days respectively. Each patch retains 0%, 25% or 50% of earlier weights respectively. Cogwick’s matchup opinions stay the same; the routes can change because the currents receive different weights.

Before sailing, Mira can call on Spymaster Fen’s network of observers. Open Spy Reports and activate Hire Spies for 300 TrustPoints to access the crew’s reports for 30 days. They scout the wider ladder and report which opponents were observed, how often, at which rank interval and over time. These are counts and field shares, not win rates. Compare their reports with your own wheel: the wider sea may have different currents. The Advisor adds available Observer counts to your own encounters before applying Phi and the seven-day limit.

Cogwick handles Global presence and Personal or Trust amplification in Evidence Alchemy. Mira handles the opponent mix, Risk Acceptance and recency in Advisor. Calculations update automatically in the background. The help marker beside Opponent mix explains the complete recipe.
