Hidden Swarm

Play this gang tactic during the End phase of any round, before deploying any Reinforcements.
Your gang may immediately deploy up to D3 Reinforcements from those fighters in your Reinforcement deck within 3" of a friendly
Leader or Champion. These fighters must be
placed within 1" of a Vent and at least 1" from
any enemy fighter. No additional Reinforcements
can arrive this round. If a fighter cannot be
placed in this manner, the fighter is deployed as
normal instead.
