[Gen 3] OU: Riders on the Storm (Rain Hyper Offense)

by Yak Attack

CB Metagross is to eliminate any wall that is in/switches in T1. I use Boom 90% of the time. T2 I switch to Ludi to set up Rain, or to try and Pump Ttar if it's in. If Ttar gets revealed later, I usually sack a mon and then trap it with ScreechLiechi Dugtrio, a set that I've come to love for its ability to survive an Ice Beam/HP Ice/EQ from the mons it wants to trap and proceed to decimate them with the lowered defense and sometimes Liechi Atk boost. Kingdra is there to put even more pressure on the opponent after Ludi is gone, if they don't have a Ludi check that also checks Dra (which is usually the case, there's another purpose, too): If that's the case, it can still serve a purpose later in the game to clean, or set Rain again to enable Hera's SalacReversal set. HP Electric is for Gyara, a mon that this team struggles with if it doesn't get Boomed on. Rock Slide is on Dugtrio because it can get the surprise Slide on a switch in if it EQs/HP Bugs without using Screech. Snorlax is to Boom on more walls to enable Ludi/Dra/Hera. Or it can Focus Punch and switch out. I usually don't use Return or EQ unless most of the opponent's team is gone and they don't have any resists. Last is the most devastating member of the team, Hera: with Rain, it can get the Salac boost and not worry about Sand chip each turn. Swarm Megahorn/Reversal does great against most threats not named Salamence/Gyarados. With +2 Atk it can even OHKO some Gengar builds.
