Team advice request

[kienever]

I'm currently trying to build a team. There are six members that I am considering: Silvegis with legend, idiosyncratic, serenity, and celestial emperor; eidrolon with Vampiric, idiosyncratic, earth emporer, and serenity; aegidron with idiosyncratic, immortality, Vampiric, and lord of the underworld; lyleen noct with stronghold strategist, serenity and vanguard; bellinoir libero with Vampiric, diamond body, siren of the void and serenity; and frostallion noct with lord of the underworld, diet lover, legend and fit as a fiddle. Any help would be appreciated
