The Battle Phase (バトルフェイズ, Batorufeizu) is the Phase in which battles are conducted. A Battle Phase can be conducted every turn except the first turn of the Duel, after the Turn Player's Main Phase 1. It is split into four main areas:

• Start Step
• Battle Step
• Damage Step (includes Damage calculation)
• End Step

For a breakdown of what occurs in the Battle Phase see "Breakdown of the Battle Phase".
