Razorkin Needlehead + Vilis, Broker of Blood + Coveted Falcon

Razorkin Needlehead

Vilis, Broker of Blood

Coveted Falcon

How it works

1. Activate Coveted Falcon by paying 1, turning it face up.
2. Coveted Falcon triggers, causing an opponent to gain control of Vilis and causing you to draw a card.
3. During that opponent's draw step, they draw a card.
4. Razorkin Needlehead triggers, dealing 1 damage to the opponent.
5. Vilis triggers, causing the opponent to draw a card.
6. Repeat from step 4 until the opponent loses the game either due to drawing from an empty library, or from having 0 life.

This fascinating loop turns Vilis, Broker of Blood against your opponent by handing them control of the demon using Coveted Falcon's disguise ability. Once Vilis is in their hands, their very next draw step triggers Razorkin Needlehead to deal 1 damage to them. That damage causes a loss of life, which in turn forces Vilis's passive ability to make that opponent draw a card, feeding right back into the Needlehead's damage trigger to repeat the entire cycle until they run out of life or cards.
