Pixies aren't really meta because any Gafc-based rush really hammers them hard because they get disrupted early on and then it's just downhill from there. The idea of WK being meta is also silly. Yeah, it's somewhat solid, but it's nowhere near set 6 strength back when Elite Fencer had sensible level 3 stats. There's more or less only one way to play it, and that's the whole violet sp-drain-with-volfied nonsense, which will get you wrecked by a ton of stuff that set 6 WK would never succumb to.
Big Lawt is strong until someone can come up with a decent Fierte file. EN can do this, but with new miff here, playing EN is sort of asking for it.
Mid refess is also decent because new Miff is broken (nerf plz) but mechanicswise, buncles (and especially SKs) abuse its dependence on DF. Dio control also roughs it up (thank goodness).
Gaiessoul splash Gowen and Refess also seem to be strong.
In any case, the big issue is that there really isn't any one good all-around meta. No matter what you play, you're going to get into some "derp whoops I'm screwed" match, almost guaranteed.
