Witch's Cauldron

{1}{b}, {t}, Sacrifice a creature: You gain 1 life
and draw a card.
Though the jars are brought to life by human
flesh and blood, they are all rather kindly folk.
Perhaps they were made to be better than their
innards. Their fragments command a high price
due to the magical power locked within. This
leaves the living jars unfortunate targets for
poachers.
