Here is my opinion on your mentioned units and their usefulness:

Alyut: Useful once you can get your light element high enough as to where you can use his SBB while having good parameters. Useless untill then.

Mikael: Usefull for the first map, but is very useful for the 2nd map's boss, since it is water element.

Chrome: Not useful early on. Could show some use once you can use 6-star units with good stats. Easily beat by omni units once you can use them with good stats.

Vernil: Useless for the 1st map, since the boss is thunder-element. Could be usefull for the 2nd map once you have leveled your water element up so that 5-6 star units have good stats. I would ony use him once you have defeated the boss of the 2nd map because that is when you unloch your 2nd unit slot.

Reud: One of the best units to use for early game. His HP regen and BB gage fill when attached buffs are really good, so he is useable on the 1st maps boss id you grind your thunder element level up.

Ciara: Not really useable until you can use 7-star units with high stats. Not recumended until then

Charla: The ideal unit for early game as long as you level up your light element so that she can withstand the bosses attacks, since she will Usually be at full HP every time an enemy attacks her.

Deimos: While I don't have a Deimos to test out, I fell like with an HP regen sphere and a Defense boosting sphere, or a BB regen sphere and a defense boosting sphere with healing items, he might be invincable. Worth a shot.

Reis: Not useful until your dark element is at a high enough level as to allow him to be at 7-star rarety with good stats. Even then, I wouldn't recomend using him

I recomend 100% completing Lin's Grand Quest if you haven't already because her HP and BB regen biffs are useful for the final boss. I also read in a comment on a thread that Finkell was useful for the 1st boss.

Also, until you complete the 4th area in the 1st map, you won't be able to summon any units. Once you can summon them, you will be very limited and only be able to summon 4 and 5-star units with stat handicaps. I would recomend one of the defensive Global Exclusive Raid spheres that were released a few days ago for deimos if you want to try to make him invulnerable.

Another thought is putting one of those spheres on a metal mimic and seeing what happens......

Overall, Inwould say that you are fairly well prepared for the 3rd arc.

I hope this helps!
