Vilis, Broker of Blood + Assault Suit + Underworld Dreams

Vilis, Broker of Blood

Assault Suit

Underworld Dreams

How it works

1. At the beginning of an opponent's upkeep, Assault Suit triggers, giving them control of Vilis.
2. During that player's next draw step, they draw a card.
3. Underworld Dreams triggers, dealing 1 damage to that opponent.
4. Vilis triggers, causing the opponent to draw a card.
5. Repeat from step 3 until the opponent loses the game either due to drawing from an empty library or by having a life total of 0.
6. When the opponent loses the game, you regain control of Vilis.
7. Repeat from step 1 for each remaining opponent.

This loop turns an opponent's natural card draw into a fatal, self-sustaining descent by leveraging Assault Suit to gift them control of Vilis, Broker of Blood during their upkeep. Once they have Vilis, every card they draw triggers Underworld Dreams to deal 1 damage to them; that loss of life immediately forces Vilis to draw another card, which loops right back into more damage from Underworld Dreams. Because Assault Suit prevents the creature from being sacrificed and happily hands it off to the next player once the current victim's library or life total runs out, you can repeat the execution seamlessly for the rest of the table.
