Evil Unleashed

This Incident is activated as soon as 20 creatures have died. Tokens only count as 1/2 for this.
Create a new player named "Endbringer"
Summon 15 5/3 Occult Golems under their control.
Give them an emblem with the text "During your upkeep, summon 2 Occult Golems. Whenever you defeat a player you gain control of their creatures.
You must attack each combat if able. Creatures you control do not tap to attack."
If Endbringer wins the game, everybody loses.
