Lamia, Angel of Blood

Flying, First Strike, Haste
When Lamia attacks, you may assign a human to
block Lamia for your opponent. You may assign creatures without flying or reach to block Lamia.
If you don't assign a blocker this way, defending
player may assign blockers as normal.
Whenever a human dies from combat damage
dealt by Lamia, return it to the battlefield under
your control with a +1/+1 counter and a flying counter, and replace its human creature type with vampire.
