but would it really help THAT much on skarm? i mean, i doubt it would do much more than 35ish% after leftovers, which isn't a good enough dent, imo. because then, skarm is always on the lookout for it, and he can easily switch into many other things on this team.
mixed sweepers are very important to skarmbliss. having just one pokemon that could do something harmful to both is not enough sometimes. it is important to have 2 pokemon who can potentially scare off skarm AND bliss. that way, it allows you to predict better, since you have multiple options, and it keeps skarmbliss on its toes. if you only had one skarmbliss "counter", it'd take a while to put skarmbliss in a corner, since it could just circle around ad infinitum. but, with two, it's easier to checkmate the skarmbliss team. it doesn't have to be major either. a slowbro with surf/dynamicpunch. tentacruel. charizard. a belly drummer/sleeper(snorlax can be devastating with lovely kiss and belly drum if you catch skarm with sleep).
