Tag out combos?

How do you tag in your next character quickly, after a grab or crumble? ( ex: Nova)

When I tag in doom after Nova air grab I can’t continue the combo, Doom’s M into launch doesn’t work I only get 1 hit from the M. When I used the crumble thing with nova and spencer, Doom doesn’t tag fast enough for me to continue the combo…

Any tips?

Sorry if this is in the wrong board.

I start from cr.:l: and just continue from there

Shameless bump.

After an air throw, you want to ADDF and whiff j.H midscreen or just ADD in the corner to give yourself enough time after Doom tags in. Then walk forward a bit and s.M (or s.H on some hitboxes). Walking forward a bit really helps. After the crumple I think you wanna do c.H then S, s.M makes them fall out.
