So can't help much with dreamer but got plenty of experience with Sandeep
First thing is, Sandeep, Banasuva and to a lesser extent with update kandara are key to how the crew works and generally if left alive will provide engine to take Sandeep to victory
However all 3 are very easy to kill especially Banasuva and so if you apply pressure to them they are likely to go down fairly quickly, or burn through stones which Sandeep needs in order to summon. So if I was playing vs your opponents crew who seems to be setting for a fire Golem, svg and emmy to be there from line is try to slow them down with a terrorfying model (say summoned insidious madness) while your own beaters try to move past them to get at Sandeeps squishy back line. As a Sandeep played I'd be happy if you put chompy/Teddy ect in to my front line as my value engine should keep them tied while my superior schemers in windgamin ect get me points and kandara gets me cards while Banasuva provides support
So in biggest trap vs Sandeep is trying to kill golems while support is still active, you will have much more luck if you target his support models first and then go if game requires go after them (you might not need to kill them to score)
So for example looking at second picture, if Lord chompy double walked forward past fire Golem to charge in the following turn Sandeep will be in real trouble.
The last thing to kind of do vs Sandeep is to anticipate the type of Golem Sandeep is likely to bring. Vs dreamer the fire Golem is the only one with meaningful damage reduction (the other two have armour which the majority of your ranged attacks ignore) and it relys on being on fire. If your can bring some condition removal against it it loses its damage prevention and then goes down pritty quickly to a teddy or chompy. I'm not sure what condition removal neverborn have, but I know iggy can remove burning fairly well so might be worth considering though more experienced neverborn players might know better
