Nice catch! I am a big fan of the Desolator. I would go with desolator, carnages, Acherons, devastators, or despoiler, hades, murders, slaughters. I also consider a Styx depending on the fleet I took. I like to keep my escorts as emergency responders and often use them as surprise strikers. Having 5-6 Infidels hit you in one turn can really hurt.
