Alice and Bob are in turn 5 of their final turns after time was called. They're 1-1, so this game's outcome will decide their match.

Alice has two cards in hand – a land and a spell with mana value >= 1. This turn, a massive amount of spells have been cast (e.g. one billion), and now Bob casts [[Ignite Memories]] with all copies targeting Alice.

As a judge, how do you resolve this game state? Bob's win is, statistically, all but guaranteed, but it's not deterministic since each copy of Ignite Memories only has a 50% chance to reduce Alice's life. What factors (such as Alice's life total, her hand composition, amount of overtime, etc.) would influence your decision? Would the ruling be different if players hadn't gone to turns yet?
