Equipped creature gets +2/+2 and has
protection from blue and from black
(A permanent or player with protection can't be targeted, enchanted, equipped, fortified, damaged or blocked by sources of the given property.).
Whenever equipped creature deals combat damage to a player,
surveil 2
(Look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.). 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.
Equip (: Attach to target creature you control. Equip only as a sorcery. This card enters the battlefield unattached and stays on the battlefield if the creature leaves.)
