General changes

Old rule (Masters Edition) New rule (Lorwyn)

Control, Controller

A permanent's controller is whoever put it into play unless the spell or ability that put the permanent into play states otherwise. Other effects can later change a permanent's controller. A spell or activated ability on the stack is controlled by whoever played it. A copy of a spell is controlled by the player who put it on the stack. A triggered ability on the stack is controlled by the player who controlled its source at the time it triggered. Objects in zones other than in play or the stack have no controller. If anything asks for the controller of an object that doesn't have a controller, use its owner instead.

A triggered ability on the stack is controlled by the player who controlled its source at the time it triggered, unless it's a delayed triggered ability. The controller of a delayed triggered ability is the player who controlled the spell or ability that created it. Objects in zones other than in play or the stack have no controller. If anything asks for the controller of an object that doesn't have a controller, use its owner instead.
