When two or more players would win the game at the same time, the game is instead a draw. This is governed by CR 104.4b, which states: 'If two or more players would win the game simultaneously, the game instead ends in a draw.'
This situation is rare but can happen with certain card combinations. For example, if a card effect would cause all remaining players to win simultaneously (such as a symmetrical 'you win' effect resolving when only two players are alive), neither player actually wins — the game is simply declared a draw.
A classic scenario: both players control a card like Thassa's Oracle triggering at the same time with empty libraries and meeting the win condition simultaneously. Because both would win at the same moment, neither does — it's a draw instead.
In tournament play, a draw is treated as neither a win nor a loss for either player, which can have implications for standings. In a Two-Headed Giant or multiplayer game, the same rule applies — if all remaining players would win at once, the game is a draw (CR 104.4b).
Note that this is different from both players losing simultaneously (CR 104.4a), though that also results in a draw. The key principle is that Magic cannot resolve a paradox of mutual victory — the game simply ends with no winner.
