The Trojan War

When the Trojan war enters the battlefield choose Trojans or Greeks.
At the beginning of your upkeep put a counter on the Trojan war then create a 1/1 red human creature token for each counter on the Trojan War if you chose Trojans. Then if there are 3
or more counters on the trojan war, sacrifice it. When the Trojan War leaves the battlefield, destroy all creatures if you chose Greeks.
