Mystic box?

If you have a mataza zapper on the field and you use mystic box does it stay on your side of the field cause of zappers effect?

It's effect does not allow its controller to change, so it would stay on your field.

You cannot activate Cards that switch the control of a Monster on a Monster of which its control cannot be changed.

This applies to cards like Mystic Box, Creature Swap, Change of Heart, etc.
Meaning that you also cannot use Mataza the Zapper for cards like these.

"Both players must have at least 1 eligible monster on the field for "Creature Swap" to be activated."

Any other questions regarding this problem?
