When USM came out i waited a little to make the thread since the tiering updates were supposed to come out shortly after but then i kind of forgot.
What happened is we lost: Silvally-Steel and Qwilfish (rip my love)
and we got: Spiritomb, Aurorus, Sandslash-Alola, Claydol
losing the best offensive spikes user and an OK defogger is definitely going to shape the metagame and what we got is quite interesting too (bar claydol)
