You'd want to keep away from Fire elements, as they could take the most damage. I'd go for Orna for Thunder attribute enchant. Lots of people I know have an Elze for an attacker (go for Guardian). An infinite SBB unit is good since the boss is only one person, which may make it hard to regain BB. Grybe looks like a good Water damage mitigator, and I also recommend a mitigator, so you can try and risk Darvenshal. A healer would be nice too, like a just-in-case unit. Get a big Thunder attacker or someone who can deal lots of damage (Hail Gigatron Reese seems good) and tag-team with Orna since GCC Holy Ice Selena has an annoying Regen buff. As for a friend, Colossal Tridon is the safest way to go, and a Tyrant Lilly Matah as leader is recommended since these units in GCC attack a lot and spam AoEs; Lilly Matah's leader skill refills BB gauge by a lot whenever attacked. Hope this helped a little, because my team was composed differently. I had a better mitigater (Ice Fortress Oulu) and a Lilly Matah, and I think I had a Tridon friend. I also had a status nullifier plus healer: Alpha Tree Altri. I hope this helped. If you want, you can add me: 95156458
