Karlana, Widow of the Glass

If a nontoken, nonhorror creature would die,
instead exile that card and create a 1/1 colorless
Bauble artifact creature token, except it has
the same name as the card exiled this way.
Baubles you control have "Sacrifice this artifact:
Choose one card from exile that shares a name
with it. You may play the exiled card without
paying its mana cost, if you do it gains haste
and is a horror in addition to its other types.
Sacrifice it at the beginning of the next endstep."
