Zelda, Princess of Destiny

Hexproof as long as it is untapped.

When Zelda enters the field, return {x} artifacts or enchantments from the graveyard to the field under its owner's control. When you deal player damage, reveal the top card of all libraries. You may cast one without paying the mana cost. The rest are placed at the bottom of the owners' libraries.

Partner. Zelda's Toughness is equal to 1 + the highest Power of creatures you control.
