What are the five phases of a turn in Magic: The Gathering?

The five phases of a turn in Magic: The Gathering are correctly identified as the beginning phase, precombat main phase, combat phase, postcombat main phase, and ending phase.

During the beginning phase, several important steps occur: the untap step, upkeep step, and draw step. Following this is the precombat main phase, where players can cast spells and play lands before combat begins. The combat phase is where players can attack with their creatures and deal combat damage. After combat, players enter the postcombat main phase, providing another opportunity to play spells or activate abilities before the turn concludes. Finally, the turn wraps up in the ending phase, which includes the cleanup step where players discard down to hand size if necessary and resolve any end-of-turn effects.

The structure provided in the chosen answer accurately reflects the layout of a turn and the specific phases within that turn, enabling players to understand the sequence of actions they can take during their turn effectively.
