If you are assuming Stealth Rock and a layer of Spikes, then to be fair Stealth Rock should be up against Ho-Oh as well. Ho-Oh will be close to death if it Brave Birds Ho-Oh twice after SR.
Deoxys-A never sweeps, it just kills something and dies next turn. Anything not weak to it's attacks can easily stop it, Jirachi, Bronzong, Palkia, Ghost Arceus, Ho-Oh, ES from Arceus, Sneak from Giratina-O...Any Scarf user defeats Deoxys-A in general. I am not saying it sucks but Deoxys-A never sweeps...
Cloyster can sweep only if it managed to smash which won't happen without Wob support. Can someone explain what's wrong with my post here, I can't see it.
<&GreatSage> if nothing else it's a "trickroom teaches pokemon" thread
<&GreatSage> which is reason enough to keep it
<@Colonel_M> I once heard Jibaku considered Scarf Gyarados for his Ubers team
