I put together some combos this morning. Watch in HD because youtube is a blurry mess.

I did a Miguel combo that CSX had mentioned in there. If you don't want Kazuya's CD4,1 to not whiff during certain tag assaults, all you have to do in most instances is a backstep before beginning to attack. You will notice me doing a back step in certain of the combos. In other cases, doing a sidestep before attacking can also help.
And as Famicom had mentioned, you really have to know Miguel's savage transitions well for him to be a viable character for you. They're not hard but you just have to go through the command list and make sure you know which moves can be transitioned into savage stance. Specifically, Miguel's d/f+1 and d/f+4,1 are very crucial for tag assaults and combos in general.
