My fear with Electric/Dark is that it just gives Rain another tool, and will increase the popularity of Electric and Water types by giving Rain a more solid answer to the Latis.
I have an answer to this (I'll have to poll-jump a bit and assume Pursuit though). An Electric/Dark
type doesn't give it any characteristics that make it less viable on Rain (or Sand), but it is outclassed on them. Rain can use Scizor or weavile as a Pursuit trapper, and Sand has Tyranitar and Scizor. The Electric typing also is out classed on Rain, because Rain already has Pokemon like Rotom-W and Thundurus-T, who lack a Ground weakness (less relevant if we give this CAP Levitate). As for beating the Lati@s, I'll link my earlier post
, where I explained how Sun has a hard time using any of the common Lati@s counters, quite a few of which fit better on Rain. And this type also has the advantage of not compounding the common type weaknesses of Sun, other than Ground. Basically, an Electric/Dark type would be mainly used in Sun, because it will face strong competition under other weathers from Pokemon that do not fit well on Sun teams.
