Charismatic Conqueror + Fractured Identity

Prerequisites

You have at least three opponents.

Steps

1. Cast Fractured Identity by paying {3}{W}{U}, exiling Charismatic Conqueror and causing each opponent to create a token copy of it.
2. When the Charismatic Conqueror tokens enter the battlefield, each opponent's Charismatic Conqueror triggers twice.
3. Because there will be two Charismatic Conqueror triggers for each token created, at least one 1/1 Vampire creature token will be generated on resolution.
4. When the Vampire enters the battlefield, each other opponent's Charismatic Conqueror triggers.
5. Repeat form step 3 using the Vampire token instead, which creates a mandatory infinite loop that will cause the game to end in a draw.
