Unblockable Assist Q

I have a pretty good understanding of how the unblockable anti-air assists work with super flashes that don’t cause block animation, but I what I want to know is whether you can time other assists to be unblockable.

Ex: You call a projectile assist and throw them, then super as the assist is in that 2-3 frame window before it hits on wake-up.

Could something like that work? Since I haven’t really seen it, I figure either it doesn’t or it’s too impractical, but thanks ahead of time.

I remember trying this with dhalsim and sentinel’s and storm’s assist and I could never get it to work.

<33 godnetro!

it shouldnt work if they are already holding back on wake up =/
