Razorkin Needlehead + Vilis, Broker of Blood + Switcheroo

Razorkin Needlehead

Vilis, Broker of Blood

Switcheroo

How it works

1. Cast Switcheroo by paying 4, exchanging control of Vilis and another creature with an opponent.
2. During that opponent's draw step, they draw a card.
3. Razorkin Needlehead triggers, dealing 1 damage to the 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 from having 0 life.

By using Switcheroo to hand Vilis, Broker of Blood over to your opponent, you set up a devastating life-and-draw loop fueled by the mere act of drawing a card. Once Vilis is safely on their side of the field, Razorkin Needlehead begins the chain reaction by dealing 1 damage to them whenever they draw. That loss of life immediately triggers Vilis, Broker of Blood to force them to draw another card, which loops right back into Razorkin Needlehead's ping and cascades into an unstoppable torrent of draws and damage that will quickly deck them or reduce their life total to zero.
