The war is progressing... now it's time for casualties.
Okay, not REAL casualties. We've all gotten to know each other, but now it's time to call each other out! In the comments, tag someone on the other side and give them a shout-out! Tell them that you really like a card they made, or appreciate their sense of humor, and of course:
Express deep regret because you intent to vanquish them on the battlefield.
