The Pikachu Cup is approaching pretty quickly, and the Smogon ladder gives potential entrants the opportunity to try out their teams. And it seems like the combination this whole thing may revolve around is an Electivire + Emolga lead pairing. Tailwind with Emolga, and go buck wild with Electivire's Earthquake. It's kind of amusing how this is supposed to be all about Pikachu, and it's another useless Electric rodent that gets the spotlight. Maybe this is going to be the thing that finally makes the powers that be realize Pikachu sucks so badly it doesn't even get used in its own tournament?
Anyway, one potential counter to the aforementioned pairing is Luxray + Rotom. We all know Intimidate is all kinds of broken in doubles, so mini-Electivire is another Pokémon that should never be used that snags the spotlight from Pikachu here. -1 Electivire is a LOT easier to handle, and a nice trick Rotom has is Snatch, to steal the opponent's Tailwind. Other fun stuff includes Soak Lanturn paired with either a Discharge user to heal Lanturn or, my personal favorite, Mega Ampharos to bypass Lightning Rod and Motor Drive with Mold Breaker. Oh, and you know the rule of thumb that Hyper Beam sucks and it should never be used ever? Well, Heliolisk likes running both it and Hyper Voice. The weird part thing is, it makes sense, because the only immune Pokémon is Rotom-N, which no one will ever use, and the only resist is Magnezone (or Magneton if you really want to go that way for whatever reason).
I'm just looking forward to seeing all the crazy stuff that people will bring there. Pretty sure Endeavor Pikachu won't be a thing, though. Between the apparent dominance of Electivire and Emolga, and Ampharos being by far and away the most useful mega out of those eligible (all TWO of them), not to mention the other neat stuff I mentioned, a Light Ball will reasonably be the best we can hope for.
