Each team consists of 5 active players and up to 1 substitute; Each player selects a unique Agent (no duplicate Agents per team); Agent roles: Duelists, Initiators, Controllers, Sentinels
Why people argue about this
People often assume that the 5 active player limit includes substitutes, leading to arguments about whether a team can have more than one substitute. Actually, the official rule clearly states each team has up to 1 substitute, so having multiple substitutes is not allowed, even if they're available through partnerships or qualifications.
