League Helper Bot helps Discord servers run balanced League of Legends custom 5v5 games using an MMR-based team generator and simple match tracking.

Core Features:

Account Linking
Use /connect to link your Riot account and get an initial MMR based on your tier and division.

Balanced Team Generation
Use /generate-teams or /generate-teams-voice to form fair 5v5 teams. The bot checks all 252 possible combinations, picks the most balanced options, and selects one for variety.

Match Tracking
Record match results with buttons. MMR updates using an Elo-style system where expected wins give smaller gains and upsets give larger ones.

Player Management
Use /attendance-check to quickly see who’s ready. Players mark availability with buttons.

Stats & Leaderboards
/me shows your MMR and info
/leaderboard displays top players
/mmr-history shows your MMR graph
MMR is tracked separately per server.

Technical Highlights
Fast team generator, Supabase storage, interactive UI, and reliable error handling.

Perfect For
Servers that host custom games, friend groups wanting fair matches, or anyone tired of manually balancing teams.

Getting Started
Invite the bot → /connect your account → gather 10 players → /generate-teams → record results and track your skill over time.
