When playing Magic: The Gathering, what happens at the end of a turn in terms of game mechanics and strategy?

At the end of a turn in Magic: The Gathering, players typically discard any excess cards in their hand and untap their tapped cards. This allows them to prepare for their next turn by drawing a card and potentially playing more spells or creatures. Strategically, players may use this time to assess their opponent's board state and plan their next moves accordingly.
