Angel of Destiny, and Mirrorweave

Prerequisites

• Angel of Destiny on the battlefield
• Mirrorweave in hand
• available

Steps

1. Cast Mirrorweave by paying its mana cost, targeting Angel of Destiny and causing each other creature in play to become a copy of the targeted creature until end of turn
2. Move to combat and declare all your Angels as attackers, sending at least one Angel at each opponent
3. When first strike damage is dealt, each Angel of Destiny you control triggers for each creature that dealt damage
4. Resolve each trigger, causing each opponent to gain life equal to X times the damage they took (where X is the number of Angels you control) and you to gain life equal to that combined total
5. Repeat steps 4-5 for the normal damage step
6. At the beginning of your end step, since your life total is at least 45, each Angel of Destiny you control triggers, causing the player it attacked to lose the game

Results

• Each opponent loses the game
