Shadowverse

One of the last battles I played today, after which I completely lost the desire to continue, was against Necropolis with the "Horn of the Abyss" artifact. I was already close to winning; I had a lot of creatures, and everything seemed good. But then, he first summoned a single unit that called out a bunch of Imps, which wiped out half of my strongest units with their last word ability and healed their leader. And as if that wasn't enough, he summoned a single Wight as the cherry on top. I had a banish spell ready to use and was planning to cast it. And what do you think happened next? This jerk summoned a SECOND "Horn of the Abyss," which gave him a bunch of Liches and another Wight.
