Corsairs of Umbar

Creature — Human Pirate

{2}{U}: Target Goblin, Orc, or Pirate can't be blocked this turn. Whenever this creature deals combat damage to a player, amass Orcs 3. (Put three +1/+1 counters on an Army you control. It's also an Orc. If you don't control an Army, create a 0/0 black Orc Army creature token first.)
