What are you even trying to say? Ebuzz checks slowbro just fine (but you won't be switching it in too often, except on a rest I guess), and just so happens to be able to 3hko nido. That's pretty nice because it forces nido to recover at some point if it doesn't want to die, giving you the advantage. Then you can switch to a nido check(/counter) like granbull/mr mime and then go on the offensive. It's also not true that lanturn and mr mime are the only counters. See:
What you are even try to say? I never said electa didnt counter bro... he counters, but he didnt counters nido! I mean, is that so difficult to understand? Bro + nido is good against electrics. Do you disagree? Do you really think that electabuzz or other electric is a good counter to a bro + nido? REALLY?
This literally makes no sense. Because electabuzz is better (or maybe it's not, whatever) doesn't mean raichu has to always click surf? You can also use tbolt? Not using surf doesn't mean you've ruined that teamslot, idgi.
I see no sense in dropping electabuzz for a raichu surfless... unless you wanna run both of them.
By this logic electabuzz is literally just as predictable, because like Enigami said surf and psychic to the same damage so uh...
No man, you dont want to switch your grass to electabuzz, since all the grass types are half poison and can be 2hko by psichyc, you want to switch to nido, see here:
Your electabuzz numbers just prove he is shut down by nido... is a 2 HKO vs a 3 HKO, do the math (also, where did i stated electaboobs didnt existed? lol). "Oh but if the player predicts correctly the switch", if a player predicts correctly every switch than he can win no matter what, thats not the point. Also, nido has LK and/or moonlight for you to take into account, nido can put electaboobs to sleep or just tank with moonlight and than earthquake it to oblivion.
