Judging by his army, everything must be reserved so he's going for an alpha strike. With your list, this give you 2 options.
Option 1 : Heavy reserve
As Jimsolo suggested, deploy only your Grots and pray they survive.
I dislike this option for 2 reasons. In your list, Grots are mean to do a good part of the heavy lifting. Even if they survive, they will be footslogging and a smart opponent is going to make sure they can't charge anything on your turn. Moreover, you don't have any mean to manipulate your reserve rolls so you will be very vulnerable if most of your reserve doesn't arrive on turn 2. I would strongly advise against this.
Option 2 : Castle
Deploy in a corner with no room for the pods to arrive between your units. Deploy outside your transports with Venoms and Reavers on the perimeter to protect your grots and your ravager as much as possible. He will be forced to drop outside your castle and if he wants to shoot at the fartest (and most valuable units) he's going to have to put himself into charging range. In this scenario you could also consider reserving your Grotesquerie to make sure it survive.
With your list, this is IMO, your best bet. If you can limit the effect of his alphastrike, you will be able to use the full power of your lance to drop his heavy hitters.
