Planewalkers are powerful beings in the Magic: The Gathering universe who can travel between different planes of existence. Each plane has its own unique characteristics, creatures, and magic. Planewalkers possess the ability to harness mana from these planes, allowing them to cast spells and summon creatures to aid them in battles. In the game, players can take on the role of a Planeswalker, using their abilities to strategize and compete against others. Each Planeswalker has a distinct personality and set of skills, often reflecting their home plane's culture and magic. This diversity adds depth to the gameplay and storytelling within the Magic: The Gathering lore.
