Covering Assists and Movement

Hey guys,

I’m playing a team of Spencer(Slant Slot)/Doom(Hidden Missiles) and Ammy (Cold Star). I’m still figuring out how to move with Spencer. I know horizontal zip can be air thrown easily so I’m using less of that. I find it very hard to move and try to protect both my assists. Are there certain moves that Spencer has to protect these assists? Coming from Street Fighter terms, I guess what blockstrings can I do with Spencer to stay safe yet maintain my pressure to counteract advancing guard?

Thank you for your time.
