That Rampardos isn't a counter to the Bronzong bejlash posted, especialy if it had Trick Roomed before (lol at Scarf + Jolly here). Assuming that, Bronzong will be going first and Gyro Ball is a OHKO on Rampardos on the switch in and EQ a 2HKO, so Rampardos wouldn't even have a chance to attack. Even if you don't assume Trick Room, Gyro Ball will still murder it on the switch in and since Bronzong has a chance to survive the 2HKO by EQ (in this case even if it doesn't won't matter), he'd also be able to hit Rampardos on the switch with EQ, survive his foe's own EQ, and finish it off with another EQ.
There's also Hypnosis which Rampardos won't like at all.

Calm 252 Hp/ 220 SpA/ 36 Spd

- Sleep Talk
- T-Bolt
- HP Ice
Imune to EQ, resists Gyro Ball (pretty sure it's not even around max power) and can take the sleep. A rip off from the analysis (couldn't be bothered to think up something else, sorry, I should be asleep by now), except with SpD switched to SpA so it can 3HKO with T-Bolt, since the SpD EVs don't matter here anyways.
