When an enemy unit with Flying is played, silence it.
Shift 5: Silence each unit in the enemy player's hand.
Card sounds may differ from in-game as they get updated.
Flying - Flying units can only be blocked by other flying units, but can block ground units normally. They can also be directly attacked by Killer units and Relic Weapons.
Silence - Remove all text from a card and its attachments.
Shift - When played, you may instead pay the Shift cost. Shifted units can't attack, block, or be selected until they emerge.
Emerge - After three turns, Shifted units emerge and get Unblockable that turn.
