2 rulings from Wizards of the Coast
- 19 March 2021If for some reason you can't win the game (because your opponent has cast Angel's Grace this turn, for example), you won't lose for having tried to draw a card from a library with no cards in it. The draw was still replaced.
- 19 March 2021If two or more players each control a Laboratory Maniac 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.
