I don't know if any of you are intending to participate in that thing, but regardless, here's a nice read on what you could potentially expect to face there. And looking at it, it's amazing just how much Pikachu sucks in this. It has no niche whatsoever, with only Plusle and Rotom-S having less of a point. Emolga's one of the most dangerous Pokémon around. Minun has a niche. Eelektrik has a niche. Dedenne has a niche. So would Electabuzz if this was a simulator thing. Pikachu... just rolls over and dies. It's pretty telling that Raichu's whole point in this tournament is playing a support role with Fake Out, Helping Hand, Encore and Knock Off, despite its defenses being shit (and by that I mean it still looks like Lugia next to Pikachu).
Hope you like Pokémiles!
