Charismatic Conqueror + The Twelfth Doctor + Benjamin Sisko, Besieged

Charismatic Conqueror

The Twelfth Doctor

Benjamin Sisko, Besieged

How it works

1. Cast Charismatic Conqueror from the top of your library by paying 1.
2. Charismatic Conqueror's demonstrate ability triggers, causing you and an opponent to copy it.
3. Resolve the opponent's copy of Charismatic Conqueror, and then resolve your copy of Charismatic Conqueror.
4. When your Charismatic Conqueror token enters the battlefield, the opponent's Charismatic Conqueror triggers, causing you to tap your Charismatic Conqueror token.
5. Resolve the original Charismatic Conqueror spell.
6. When the nontoken Charismatic Conqueror enters the battlefield, the opponent's Charismatic Conqueror triggers, causing you to not tap the nontoken Charismatic Conqueror, and causing the opponent to create a 1/1 Vampire creature token.
7. When the opponent's Vampire token enters the battlefield, both Charismatic Conquerors you control trigger, causing you to create at least one 1/1 Vampire creature token.
8. When your Vampire token enters the battlefield, the opponent's Charismatic Conqueror triggers, causing you to not tap the Vampire token, and causing the opponent to create a 1/1 Vampire creature token.
9. Repeat from step 7.

This fascinating loop starts by leveraging Benjamin Sisko, Besieged to play Charismatic Conqueror from the top of your library as though it were being cast from somewhere other than your hand. Because of this, The Twelfth Doctor grants the spell demonstrate, allowing you to copy it and flood the board with multiple token copies alongside the original. Once these permanents are in play, their own triggered abilities feed into each other in a continuous cycle: whenever a creature enters untapped, an opponent is forced to choose between tapping it or handing you a 1/1 white Vampire creature token with lifelink, which in turn triggers your other copies to generate even more tokens for an endless chain of entries.
