That's what we came up with till now. Replaced the Sslyth as my Archon will probably only sit back to hold some objective or generate CPs. With the extra points from Sslyth and razorwing flocks I added 5 warriors and some heavy weapons.
My friend decided to use a Trygon to deep strike 20 devourer gants, because in 2 of 3 missions deep striking in the first round and outside the own deployment zone is allowed. Furthermore, there is a good portion of Tau players which makes it difficult to build a CC army with these restrictions.
Overall battle plan: Gants kill the small critter, dark light weapons blow up tanks, the rest cleans up the remainings.
