Sword of Once and Future

Equipped creature gets +2/+2 and has
protection from blue and from black.

Whenever equipped creature deals combat damage
to a player, surveil 2. Then you may cast an
instant or sorcery spell with mana value 2 or less
from your graveyard without paying its mana cost.
If that spell would be put into your graveyard,
exile it instead.
