Shredder, Shadow Master + Bloodletter of Aclazotz

Shredder, Shadow Master

Bloodletter of Aclazotz

How it works

1. Declare Shredder as an attacker. Shredder's first ability triggers, creating a tapped and attacking copy of it attacking each other opponent that isn't legendary.
2. Deal combat damage using the Shredders. Each Shredder triggers, causing each opponent to lose their entire life totals due to Bloodletter of Aclazotz. Each opponent then loses the game due to having 0 or less life.
