GIVE EO WARSTORY
@Thund: Muk can only setup on Earthquake-less Venusaur, something Registeel can do as well. However, Registeel doesn't take skyhigh amounts of damage because of some surprise Eathquake.
@Heysup: Huge block of text... but regarding what Eo said about Venusaur KOing Weezing, he means you can do the following: Sleep the Weezing switch, Leaf Storm Weezing (1 turn asleep), switch out and bring something that threatens an OHKO (2 turns asleep). The next time you bring in Venusaur Weezing can no longer switch in because it will be KO'd by the Sludge Bomb on the switch and the subsequent Leaf Storm. I agree that's indeed very situational though.
On another note, if you wanna be 101% safe against Venusaur, use Registeel and Weezing. SD (except for those that carry Return and are extremely lucky) and mixed sets with Earthquake are completely walled by Weezing, while Special sets are countered by Registeel. The only possible combination of attacks that could break the duo is Swords Dance/ Earthquake/ Power Whip/ Return; but that would mean no Sleep Powder to gamble with Weezing and some recognizeable overall suckiness. The two of them together are no absurd combination as well (Weezing resists Fighting and Ground, while Registeel takes on Psychic hits). Finally, I wouldn't call it absurd to run the two of them and make yourself completely safe against the number pokémon, especially when many others like Clefable go through the same thing (no, Hitmontop cannot beat Calm Mind LO Psychic. Yes I've gone that far, because this is no more absurd than many arguments I have been reading in this thread.)
