Altanak, the Thrice-Called

Sentinel

Lure

Blim, Comedic Genius

How it works

1. Deal combat damage to an opponent using Blim.
2. Blim triggers, giving control of Altanak to an opponent.
3. Declare Sentinel as an attacker, forcing Altanak to block it due to Lure.
4. Holding priority, activate Sentinel an arbitrarily large number of times by paying 0, targeting Altanak.
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.
