God-King Xerxes, Obliterated

As long as your devotion to white and red is less
than eight, King Xerxes isn't a creature.
When King Xerxes leaves the battlefield, if he
was a creature, create five 3/1 red and white
Human Warrior creature tokens with trample
and haste. Then put 5 +1/+1 counters on all
creatures you control.
{7}: Sacrifice King Xerxes.
