Atemsis, All-Seeing + Legion Loyalty + Mirror Box

Atemsis, All-Seeing

Legion Loyalty

Mirror Box

How it works

1. Declare Atemsis as an attacker.
2. Atemsis' myriad ability triggers, creating a token copy of Atemsis tapped and attacking each other opponent.
3. Deal combat damage using each Atemsis, triggering their abilities.
4. Resolve each Atemsis trigger, causing you to reveal your hand and causing each opponent to lose the game.
