Unbreakable Alliance

When Unbreakable Alliance enters the
battlefield, choose an opponent. You and that
player each draw two cards, gain 5 life, and
search your libraries for a basic land card, put
them onto the battlefield tapped, then shuffle
your libraries.
Creatures you and the chosen player control
have protection from creatures. You and the
chosen player can't attack each other unless
there are no other opponents.
