Read the matchup, find their fatal flaw.
Drop both team comps. We classify each side, surface the single weakness on their team you can abuse, and hand back the phase-by-phase plan that closes the game.
About the Win Condition Analyzer
The Win Condition Analyzer is YordleDiff's free League of Legends draft tool that classifies both team comps into one of eight archetypes and produces the head-to-head plan to play around them. It's built for ranked players who want a fast, defensible read on a draft — without the hand-wavy "your comp is good in teamfights" advice that doesn't translate to actions. Pair it with the Team Builder if you want bans, builds and the jungle path on top.
How does the Win Condition Analyzer work?
methodologyEach champion has per-champion macro signals — engage, mobility, disengage, waveclear, scaling, frontline weight and tempo. The analyzer aggregates those signals across the five-man comp, scores it against each of eight archetypes and picks the best fit. It then runs the same on the enemy comp and produces the head-to-head verdict, a phase-by-phase script and the enemy's single most exploitable weakness.
Why does the page lead with their fatal flaw?
design rationaleMost of the value in a comp analysis is in one sentence: what's the one thing about their comp you can attack right now? Everything else — the archetype names, the macro bars, the phase script — is supporting evidence. The flaw card is the headline because it's the answer.
What rank do the stats come from?
data sourceThe per-champion signals are derived from current-patch (16.10) macro ratings calibrated against ranked Emerald+ game data. Comp classification is 100% per-champion signal — no hand-picked comp templates or opinion-based tier lists.
