Marisa is not an easygoing shot either when it comes to optimal play, since her shot is a motherfucker. I will not say that they would be bad for low-effort 2b scores, but if you want to hit a "low-effort high on the lists"-score you should play the teams - youkai partner eases stuff a lot.
And I'm pretty sure you could break 2b with any of the shots, barring youkai solos, Railgun. All it would need should be some finesse in the routes. But I am rather sure that you could at least hit 2b, if not compete with me.
