Jester of the Masquerade

You may have Jester of the Masquerade enter the battlefield as a copy of any creature on the battlefield.
Creatures your opponents control that have the
same name as this creature become tapped and do
not untap on their controller's untap step. Those
creatures cannot attack or activate mana abilities.
{2}{u}{u}: Return this creature to its owner's hand.
Any player may activate this ability.
