Smash Legend
Basically, ICs don't have an attack that covers the space above and in front of them very effectively. Floating with aerials is therefore a very strong general strategy against them, with where you can occupy.
Beyond that, just kill Nana with some semblance of efficiency since FC nair > more FC nair > fair her out of her DJ is a death combo and you can fend off her lover easily enough.
If you d-smash an ICs' shield, WD OOS grab can kill you. So don't be reckless with d-smash if they're decent. Dash attack is bad for similar reasons, as is wake-up attack.
