Altanak, the Thrice-Called + Soltari Guerrillas + Coveted Falcon

Altanak, the Thrice-Called

Soltari Guerrillas

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 Altanak and causing you to draw a card..
3. Activate Soltari Guerrillas an arbitrarily large number of times by paying 0, targeting Altanak.
4. 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 delightfully devious loop uses Coveted Falcon's face-up trigger to hand your opponent ownership of Altanak, the Thrice-Called, turning their side of the board into a trap. Once Altanak is safely in your opponent's hands, you point Soltari Guerrillas's redirection ability at it an arbitrarily large number of times using its zero-mana activation. Each targeted activation triggers Altanak's static-like defending ability to force your opponent to draw cards until their library runs completely dry and they lose the game.
