Teams alternate banning champions (5 bans per team, 10 total); Ban phase: 3 bans each → 3 picks each → 2 bans each → 2 picks each; No champion may be picked or banned by both teams
Why people argue about this
People often assume that champions can only be banned once per draft phase, thinking it's a simple ban-pick cycle. However, the actual rule is that no champion can be banned or picked by both sides in a single match format, which complicates their understanding of how bans and picks work together across different tiers.
