Ghost-Pack Alpha

Alpha gets +1/+1 for each Ghost Wolf you control.
{w/b}{w/b}{w/b}, {t}: Choose Call Pack or Feed Pack.
Call the Pack- Create two 1/1 black/white Ghost
Wolf creature tokens, if an opponent has no creatures under their control then untap Alpha.
Feed the Pack- Target player must sacrifice a creature, if that creature's power was less than
Alpha's then each opponent takes damage equal
to the number of Ghost Wolf creatures you
control and you heal for that much.
