Altanak, the Thrice-Called + Martyrdom + Coveted Falcon

Altanak, the Thrice-Called

Martyrdom

Coveted Falcon

How it works

1. Cast Martyrdom by paying 1, targeting Altanak.
2. Activate Coveted Falcon by paying 1, turning it face up.
3. Coveted Falcon triggers, causing an opponent to gain control of Altanak and causing you to draw a card.
4. Activate Altanak an arbitrarily large number of times by paying 0, targeting itself.
5. Altanak triggers that many times, causing an opponent to draw that many cards and lose the game due to drawing from an empty library.

This eccentric puzzle transforms Altanak, the Thrice-Called into a weapon of mass drawage by leveraging Martyrdom to weaponize its target-redirection ability. Once Coveted Falcon is turned face up via its disguise cost, you hand Altanak over to your opponent, making them the controller of the target of a spell or ability you control. This sets up a vicious loop where you can repeatedly activate the zero-cost redirection granted by Martyrdom, targeting Altanak an arbitrarily large number of times and forcing your opponent to draw out their entire library until they lose.
