What are the different MTG phases and how do they impact gameplay?

In Magic: The Gathering, there are five main phases in a turn: beginning, pre-combat main, combat, post-combat main, and ending. Each phase has specific actions and opportunities for players to play cards and make strategic decisions. These phases impact gameplay by allowing players to cast spells, attack with creatures, and strategically plan their moves to outmaneuver their opponents. Understanding and utilizing these phases effectively can greatly influence the outcome of a game.
