Steamroller Pairing

It looks like what you'll most want to consider pairing with that Absylonia2 list is something that can take on infantry swarms.

Absylonia1 and Thagrosh2 don't do that particularly well, so you can probably leave them out.

Rhyas1 has a pretty similar all-in melee thing going on as Absylonia2, so it might be good to diversify a bit in the second list.

Thagrosh1 and Fyanna2 largely address infantry defensively, although they both have some tools to take an offensive strike.

Lylyth1/2 are very offensively-oriented, and can support higher volume of ranged fire, with Lylyth2 bringing more shots and Lylyth1 putting out higher accuracy.

All that said, if you know the popular things in your meta that can go a long way, otherwise I'd go with whatever sounds most interesting.
