Shiv, Raging Hunter

When Shiv's toughness reaches 0 he is not destroyed until after the next combat phase,
but his toughness is not restored in the end
phase. If his HP goes above 0 before then he
will not be destroyed. It works.
Shiv gains +2/0 every time he attacks.
{3}, destroy target creature with toughness 2 or less.
