Result
Win rate, verdict (Dominant / Favorable / Contested / Unfavorable / Bad), and best strategy. Free users see win rate and verdict. T2 unlocks the full analysis below.
① The Takeaways
Three stat cards: Strategy confidence (how much better the best plan is vs the next-best), Pressure breakpoint (first turn you take AP advantage), and Tactical edge (the resource category with the largest gap).
Average turns to win, average game length, and preferred start (first vs second win-rate split).
③ The Game Over Time
Turn by turn: a timeline strip with shields, units, and AP pressure per turn. Click a turn to see the Most Likely Board — which units are typically in play, their health, and how often they attack, block, pair, link, or use effects.
Tactical resources: tracks Blocker, Breach, Card Draw, Energy, Repair, Hi-Man, Extra Attack, Direct Damage, Rest, Bounce, Destroy, and Tokens per turn for both decks. Filter to a single resource to focus on what's deciding the matchup.
