Changeling Sweep

Promotion card from All Good Things (2003)

Changelings will be forced into a gelatinous state by a mid-level phaser stun. In 2372, special units were placed in many Starfleet facilities to ensure that empty rooms were in fact truly so.

Plays to "sweep" an opponent's discard pile: examine it and place any interrupt cards (except or cards) out-of-play.
