Phase

Each player's turn is comprised of six Phases. These six Phases continually cycle, alternating between players until a winner is declared.

Main Phase 2

After the Battle Phase, the Turn Player enters Main Phase 2. In this Phase, any action that could normally be performed in Main Phase 1 can occur, as long as the requirements are met (i.e. no more than 1 Normal Summon or Set).

End Phase

Once Main Phase 2 (or Main Phase 1 if no Battle Phase was conducted) has been completed, play proceeds to the End Phase. Any card effects that resolve in this Phase now take effect, such as "Change of Heart" or "Brain Control". The Turn Player gets to decide in which order any effect resolves.

If the Turn Player has more than six cards in his hand at this time, he/she must discard to the Graveyard as many cards as necessary in order to get back to six. This action is the very last thing to happen in any End Phase.
