Siege of Gondor

Amass Orcs 2. When you do, Siege of Gondor
deals X damage to target creature an opponent
controls, where X is the amassed Army's
power. (To amass Orcs 2, put two +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.)
