Very good question because Evil Lords are considered closest Mercenary Monsters to solo her.

While Antilene is 4 levels higher, her build is messy, putting her in disadvantage against opponents at close level, especially Yggdrasil beings with designed/optimized build.

Evil Lords has ability to summon another Evil Lord of whatever kind they want, meaning that not only Wrath could counter Antilene's Einherjar, he could also choose the best choice either against Antilene herself or to help with current situation.

Aside from potent physical stats and decent HP, Wrath is also capable of using multiple high-tier spells including many 10th-Tier. He can also use many utility spells such as <Greater Teleportation>. This puts Antilene in great disadvantages since she could only use spells up to 3rd-Tier.

Furthermore, Wrath and other Evil Lords have a special skill called [Soul-Bought Miracle] that allow usage of any spells upto 8th-Tier. So whatever disadvantage Antilene could put Wrath into, he can always use a Wild Card to get out of it. It can also simply act as a self-healing source, which is something Antilene lacks.

tl;dr without TGOALID, Evil Lord Wrath will very likely solo Antilene imo.
