Both Razorwing have DL
The beast are a combat threat, but I feel that with all the Wywern out there, they will give an easy first blood.
The strengh of the first list is that both Blasterborn can be deep striked, the one with Archon using WWP, and the other one as the Venom is quite small and should fit where needed.
On the other hand, Grotesques and Succubus can't really go wrong.
