And so Shelly has fallen. I have to say, this gym was traumatizing for the dark run. Unfortunately mightyena didn't work, but after many resets skuntank did.
Mono dark, I couldn't use it. Although Shade is going to be a piece of cake. (And of course....right AFTER Shelly you can get houndor, but not before.)
.Vulpix rips through Shelly with Flame Burst aswell
