FAQ
A Scowly Caper (AoA 313) that I own and my opponent controls is purged with Spangler Box (CoTA 132). Later, the Spangler Box is destroyed. When Scowly Caper returns to play, whose control will he be under?
When the Spangler Box returns Scowly Caper to play, this counts as “entering play” again, so Scowly Caper’s ability again causes you put it into play under your opponent’s control.
