Good counters for the Dwarven Door continuous defense loop?

Hey guys,

I have been slowly and painfully making my way through the PVP bonuses/events this week by pitting my Dwarven offense team against whatever Dwarven defense teams I can find. As I’m sure you all know by now, nothing is more tedious that trying to take out a Dwarf team with another Dwarf team.

However, I just had a battle that went beyond tedious to unbearable. My Dwarven offense team (Dwarven Gate, Apothecary, Lady Ironbeard and Runesmith) took on a Dwarven defense team that was comprised of 3 Dwarven Gates and 1 Valkyrie. To me it looked easy and was worth 3 trophies, so I gladly started the battle…

…and found out rather quickly I had made a terrible mistake. See, with 3+ Dwarven Gates, the spell can potentially continuously loop…which is exactly what the AI did to me. Valkyrie quickly filled up the first 2 Dwarven Gates, and then one cast its spell. The next turn, the second one cast its spell, which gave the first Gate 5 mana and filled up the third gate (which had 5 mana already from the first cast). Then, the third one went off and well…you see where this is heading. With the gates constantly casting and barriering, I was stuck at a stand still. Sure, I wan’t getting damaged, but I in turn could not cause damage either. After 20 minutes, I retreated and called it a day.

Has anyone figured out a good counter for this team yet? Obviously, Famine or any other mana drainer would make the most sense, but none of the mana drainers out there are Dwarfs. Thanks in advance!
