Thanks! I've been seeing Therians and more Genesects recently. It felt like a massive overdose of Therians when they were first released, but things have settled back to the normal routine. Genesect with scarf is so hard to defeat (without Heatran)... it a solid contender in the OU battleground.
My personal favorite volt switcher is Thundurus-T scarfed though, it hits ridiculously hard with decent speed. I can't decide whether Genesect or Scizor is better though, both serve different purposes admirably.
Smogon's October simulator statistics seem to match what I've been seeing a lot of, except for Ferrothorns. Barely saw any recently.
