In Magic: The Gathering, you are counted among the elite spellcasters of the Multiverse—the Planeswalkers. Your deck of cards represents your weapons, containing the spells you know and the creatures you can summon to fight for you. Games are played by two or more players, each of whom has a customized deck of Magic cards. Each player starts at 20 life. When you reduce your opponent to 0 life by attacking with creatures and playing spells, you win!
