Assist combos help?

My current team is Zero, Super Skrull/Deadpool, Doom. I just can’t seem to find any combinations of assists to extend any combos. :[
If you have any suggestions, please tell me, because I’m not great at this game. =
I’m also open to changing order, my second, or anything. Is there a character that would compliment Zero and Doom better?

Doom’s missiles literally extend everyone’s combos.

Dante works amazingly with Zero. Strider works amazingly with Doom.

Take a look at the team building thread for further details, this will most likely be closed soon.
