Pick both teams once. Get bans, win conditions, then drill into the build, runes, matchups, or pair synergy for any ally — live, all from the same draft state.
Team Builder is YordleDiff's flagship champ-select coach for League of Legends 5-stacks (and solo queue players who want to plan a draft in seconds). Pick your five allies and up to five enemies and the tool produces aggregated bans, comp-aware item builds for every ally, both teams' win conditions, and the jungler's jungle path — all in one shareable URL. It bundles every other tool on the site into one canvas, so a duo or premade can plan the whole game without bouncing between tabs.
As you pick champions, four engines run in parallel. The ban engine sums per-matchup pain scores across your team, so the bans that hurt the most allies float to the top. The build engine ranks items by the Wilson lower bound on win rate against the specific enemies you've picked, swapping in comp-specific picks when statistically warranted. The win-condition classifier maps both team comps to one of eight archetypes and produces a tempo read. The jungle-planner embed reads the full draft for counter-intel on the enemy jungler.
Yes. The complete draft state lives in the URL, so paste the link into voice chat and everyone sees the same picks, bans, builds, and game plan. Bookmark the URL and you can re-open the draft after the game to review.
All recommendations use ranked Emerald+ data on the current patch (16.11). Pair-synergy and per-matchup item stats require enough sampled games to be Wilson-stable, so the picks don't shift wildly between page loads.
Yes. Team Builder and every other tool on the site are currently free to use, with no login or signup needed. The whole tool runs in your browser — nothing you enter is uploaded.
