Creature - Minion 3/3, B (1) When Sleeper Agent comes into play, target opponent gains control of it. At the beginning of your upkeep, Sleeper Agent deals 2 damage to you.
Illus. Randy Gallegos
This card is a bit weird. When it comes into play under your control, you give control of it to an opponent. After that it damages them each turn because the "you" on the card means its controller. [D'Angelo 1998/10/15]
