Spoiler: The stage setup Video of me trying out a 4* run. Second video, with better results but still a loss. I have another idea on how to make this particular team work, I'll upload another video as my stamina becomes available for another run. Important things to note is that both ninjas deal bonus damage to infantry units, Ursula deals bonus damage to cavalry, and the sword-cavalry unit has the "block" ability, so units cannot pass by him, as you can see I suffered to that skill in the video. I believe that you can beat this stage comprised entirely of a team with free units-- those units being Lissa, Oliva, Robin (F), and Celicia (instead of Robin(M)) in that order. First unit is at the top-left, 2nd unit below 1st, 3rd unit below 2nd, and 4th unit to the right of the 2nd unit. Team breakdown is that you use Cecilia (or in my case Robin(M)) to aggro all of the ninja attacks to wound the first one and kill the second one. Lissa has the skill Imbue equipped to fully heal Robin(M) after aggro, and Olivia would dance to have Lissa Imbue him right away. Robin (F) as you can all see, moves to a spot where Ursula kills herself on her the first turn. After that I think where I went wrong in the video is that I did not take the opportunity to kill the armored unit with Robin (F) and flee with sing, but instead sung on Lissa to fully heal Robin(M) instead, even though he could've taken a hit from the cavalry unit anyway. That said, if it was a Celicia, she would've died to this course of action. As for Ursula herself as a unit, she seems like she could be pretty good! Outclassed by the most recent blue-tome cavalry sure, but if her 5* stats are good, she has respectable damage potential with threaten RES and death blow skills, not even considering her bonus damage to cavalry units. Certainly a unit worth picking up this time around, but her worth remains to be seen in her 5* form.
