The Goddamn Batman said:Normally, I handle Ludicolo by paralyzing it, and then hitting it with strong neutral hits. On my team, this is how i usually handle it. Ludicolo takes SR damage, and then i paralyze it with Uxie. I U-turn out to Rotom-C to take the Surf, which can hit it with a strong Volt-Switch. I bring in Entei on the Ice Beam, and Flare Blitz for the KO. Of course, the conditions are not always great for this, but the moral of the story is that the easiest way to take down Ludicolo is to paralze it, resist its hits, and attack when you have an opportunity. Also, if Ludicolo is being used on a Rain team, this method of takedown is also good because you waste turns of Rain.
If that method doesnt appeal to you, Unburden Hitmonlee can come in on anything other than Surf/Hydro Pump, use Fake Out, activate Unburden, outspeed and KO with HJK/CC.
I think he was looking for reliable counters, not using someone else's team and predicting :p
Nothing can really both take a hit and OHKO Ludicolo, since Ludi will be faster in rain. Some stuff that can actually take Ludicolo's moves:
Hydro Pump vs.
252 HP / 252 SpDef Cryogonal: 36.91 - 43.89%
136 HP / 248 SpDef Munchlax: 26.29 - 31.01%
252 HP / 252 SpDef Roselia: 19.73 - 23.68% (Ice Beam: 42.1 - 50%)
252 HP / 0 SpDef Regice: 32.41 - 38.18%
252 HP / 252 SpDef Mandibuzz: 38.2 - 45.28% (Ice Beam: 40.56 - 48.11%)
Basically those are the only decent Pokemon that can take a few hits, and 3 are weak to Stealth Rock. I wouldn't really worry much about Ludicolo in rain because they aren't too common. Your best options are paralyzing it, stalling out rain or hitting it hard with priority. The priority that hits Ludicolo the hardest is Honchkrow's Sucker Punch (80 - 94.42%).
This makes me want to use Ludicolo lol.
