Legendary Creature — Shapeshifter 3/3, UUBB (4)

Hexproof

Whenever a creature card is put into an opponent's graveyard from anywhere, you may have Lazav, Dimir Mastermind become a copy of that card except its name is still Lazav, Dimir Mastermind, it's legendary in addition to its other types, and it gains hexproof and this ability.
