When copying a permanent, what choices does the controller get to make?

When a permanent is copied, the controller of the copy gets to make new choices for the copied object. This is because the copy is a new object with its own characteristics that are derived from the original but don't carry over the original's previous choices.

For instance, if the original permanent had abilities that allowed the controller to make specific choices, those choices pertain to what the original controller decided when activating or using those abilities. However, when a new copy of the permanent is created, it is treated as a new object entirely, allowing its controller to determine how that copy will function within the game.

This means decisions concerning how to use any abilities that the copy might have, what choices to make regarding its characteristics, and even how it interacts with the game state at the time it enters the battlefield can all be made anew. Therefore, the idea that the controller has the ability to make new choices with the copied object accurately reflects the way copying mechanics work within the game's rules.
