Ambush (After you play this unit, he may ready and attack an enemy unit.)

When you play an event: You may deal 2 damage to a unit.

Rules Clarifications:

• Ambush is an ability that triggers at the same time as “When Played” abilities. If there is no enemy unit that can be attacked, the unit does not ready.
• Bossk’s “When you play an event” ability triggers when an event is played but only resolves after the event has fully finished resolving.
