Hive Mind + Leveler + Theoretical Duplication

Hive Mind

Leveler

Theoretical Duplication

How it works

1. Cast Theoretical Duplication by paying 2.
2. Hive Mind triggers, causing each other player to copy Theoretical Duplication.
3. Resolve all copies of Theoretical Duplication.
4. Cast Leveler by paying 5.
5. Leveler's ETB ability gets put on the stack, followed by each other player's delayed trigger from Theoretical Duplication.
6. Resolve one of these Theoretical Duplication abilities, creating a token copy of Leveler under another player's control.
7. That player's Leveler's ETB ability triggers, exiling that player's library.
8. Repeat the previous two steps for each other player.
9. Your own Leveler's ETB ability resolves, exiling your library.
10. Each opponent will lose the game in their draw step for failing to draw from an empty library.
