Doc Holiday of Tombstone

Whenever a creature you control would die,
you may pay X, where X is its mana cost, if you do regenerate it.
Whenever one or more creatures attack you, deal damage equal to the number of creatures
attacking you to target creature.
There was something very peculiar about Doc. He was gentlemanly, a good dentist, a friendly man, and yet outside of us boys I don't think he had a friend in the Territory.
