How to beat subterannean assault??

hello!

I have played against this detachment maybe 5 times now, and have gotten trashed every single time.

for context, i usually play dark angels and this is how the games usually go:

- deploy, then most big bugs jump into reserves

- spend turn 1 moving up onto objectives and into position

- raveners jump out turn 2, make tunnels and every other bug jumps out within 6 inches and I lose most of my army

- game basically over by this point

I am just looking for advice either from players playing against this or players who use it as to what is the best counterplay for this strategy.

Obviously there are certain units that I could take to create a deep strike bubble but I dont want to skew my list too much for one single matchup.

I feel its particularly difficult to deal with as an elite army, as I dont have many units to deny deepstrike effectively. I usually play scouts, but often, if i push them too aggressively to deny deepstrike, they get gobbled up by a lictor and then Ive lost my only screening units.

I am so lost as to how to play against this, any help would be hugely appreciated!!!!
