How it works
Cast Enter the Infinite by paying 8.
Hive Mind triggers, causing each opponent to create a copy of Enter the Infinite.
Resolve each Enter the Infinite, causing each player to draw their entire library, put a card from their hand on top of their library, and have no maximum hand size until their next turn.
At the beginning of each opponent's draw step, Dictate of Kruphix triggers, causing them to draw an additional card and lose the game due to drawing from an empty library.
