Lenore, the Last Heiress

Invincible, hexproof
Whenever a creature dies you may pay three life,
if you do create a token that's a copy of that
creature except it's 1/1, and a Zombie in addition
to its other types.
If Lenore would be sent to the graveyard, exile it instead.
{2}: Target creature you control gains vigilance
until the end of the turn.
