Jace, Wielder of Mysteries

If your library has fewer than seven cards in it while resolving Jace’s last ability, and Jace has already left the battlefield, you’ll draw as many cards as you can and then win the game before state-based actions would cause you to lose the game for trying to draw from an empty library.

Follow the instructions in the order listed on Jace’s first loyalty ability: if you target yourself, you’ll put the top two cards of your library into your graveyard and then draw a card.

If two or more players control Jace, Wielder of Mysteries and each player is instructed to draw a number of cards, first the player whose turn it is draws that many cards. If this causes that player to win the game instead, the game is immediately over. If the game isn’t over yet, repeat this process for each other player in turn order.
