was messing around with some builds on a mass duel simulator (link is https://andu2.github.io/FEH-Mass-Simulator/ if you were wondering) and found a nice little Black Knight build (no merges or IVs obviously)
Brave Sword +
Pivot
Black Luna
Death Blow
Bold Fighter
Armor March
Quickened Pulse
so basically he is able to proc black luna twice in his first engage and also quad hits every engage. checking the mass duel simulator he wins against every single unit except for sully on engage due to color disadvantage and sword breaker. now I know that this checks his battles against units with their default skills but still that is pretty insane all things considered. Even after setting all enemies to +10 merge he still wins against all but 8 units and only losing to 1 of those 8 (he loses to Oboro). Of course you can run Odd attack wave for even more insanity but thats a bit more expense than I have access to. Fortunately (or maybe not) I had a Winter Lissa about five minutes ago, lets just say shes gone now and my black knight is VERY happy. Anyway I just wanted to talk about other absurd stuff people have found like this. Basically making an enemy phase unit into a player phase god because of black luna's immense power. So you if you have a weird build that completely changes the expected playstyle of a unit please tell me.
Well, i am the holder of a very peculiar Shanna. Rather than any more obvious player phase sets, she has become my flier emblem tank, she can function multi-phase but is much better as an enemy phase tank. I plan to give her tannenboom! sometime in the future to increase her usability. Mixed bulk is fun
