Sar'Gol, the Risen

Sar'Gol, the Risen can't be blocked by creatures
with greater power than its current power.
Whenever Sar'Gol would deal combat damage to
a player, it gains double strike.
Whenever Sar'Gol, the Risen or another Zombie
you control with power 4 or greater would deal
combat damage to a player, you create half that
many 2/2 Zombie creature tokens.
