Which dancer unit should I use in my arena defense team?

HS!Micaiah as she's one of the Bonus units and she has a good iv.

From what I hear, the recommendation is melee dancers because they're harder to bait. I'm not sure if that's going to hold true with your Micaiah because she's actually quite a dangerous unit and not necessarily easy to bait, especially if your opponent has a lot of armour.

Now, from me and not from others:
- I like YT Olivia because people might forget to factor in Skuld bonuses when trying to bait, and they might very well have to when you have L.Ephraim and Myrrh, also if your Ike uses QR.
- I also like YT Olivia because chill spd will screw with people in an extremely annoying way. You could substitute wings of mercy if you think one of your units might be able to drop into low health without already having taken out an opponent. It would make Myrrh harder to bait with someone like Fir or Caeda because those units won't be able to double Myrrh back without QR. But I would expect most opponents to try to bait Myrrh using some QR tank (or Alfonse, who may very well double because he has the def to compete with Great Flame)
- I don't see an advantage to using Azura or Ninian over your other two melee options because of Skuld bonuses.
- does your team have a bonus unit? I don't have the bonus roster memorized.

Currently running Micaiah on my defensive team and she’s a good unit, especially with the atk boon
