Witch King of Minas Morgul

Fear, Ward {4}
Whenever an opponent player casts an instant or sorcery spell, that player mills two cards and you amass Orc Warrior 1 (Put a +1/+1 counter on an
Army you control. It's also an Orc Warrior. If you
don't control an Army, create a 0/0 red Orc
Warrior Army creature token first.)

Every time a creature you controll deals combat damage to a player, you gain 1 life.
