Vulcanic Thomb

When you cast Vulcanic Thomb, choose a
creature type.
As long as you own at least one creature of the
chosen type on your side of the field, put a 1/1
black and red Vulcanic Larva creature token onto
the battlefield at the beginning of your upkeep.
If the last creature of the chosen type is put into
your graveyard, sacrifice Vulcanic Thomb and
discard two cards.
