unending manipulation

When this enchantment enters, look at the top card of each opponents library, then exile them face down. You may play those cards for as long as they remain exiled, and mana of any type can be spent to cast them.

Whenever you activate an ability of a permanent you control but don't own, copy that ability. You may choose new targets for the copy.

If a triggered ability of a permanent you control but don't own would trigger, that ability triggers an additional time.
