Nohr Noble +spd/-luck stats for my reference since the topic doesn't have them and lol as always using something that can't actually exist
41.0/26.45/20.05/25.45/36*(+1 w/Yato)/14.45/25.0/23.1
20.45 w/Shadow Yato, 13.05 w/Levin Sword, 14.05 w/DS, 25.05 w/DS+, gives her something like +7.5 raw avoid and -2.5 raw hit.
some exceedingly half-assed average tinkering puts spd average at 25.9 and damage average at 20.94/52.35
of course while I don't vote based on Birthright Corrin it's only fair to apply the same treatment to the Birthright cast here so:
42.0/29.45(+4 w/Yato)/16.25/27.25/34*(+5 w/Yato)/17.25/23.6/11.7
28.45 w/Blazing Yato is all I care about here, so we get 29.77 avg spd and damage at 20.74/51.86Corrin vs.
Ryoma - So +spd Corrin doubles, that's the good news. The bad news is uh Ryoma still has 51% evade (less on subsequent turns granted but still cause for concern) and still has a range advantage so all the doubling is doing is offsetting that. They 3HKO each other but yeesh Corrin hopes that -luck doesn't matter. Levin Sword is basically suicide, oh boy a range 2 counter Corrin won't hit with ever in exchange for dat evade drop.
Corrin vs. Hinoka - Hinoka doesn't double +spd Corrin on her own turns (and is getting doubled herself regardless), but WTA is still a thing since Dragonstones sort of don't work out too well here, probably Corrin though, Hinoka offense without doubles is pretty bad and Bolt Naginata isn't helping her much (not too sure about allowing with like 5 potential users but yeesh, 3/5ths of them are just openly terrible with it).
Corrin vs. Takumi - This probably works out.
Corrin vs. Sakura - ORKO, having Levin Sword counters here is just icing.
Corrin vs. Xander - Levin Sword
Corrin vs.
Camilla - maybe DS+ x2 would work with +Skl (except this gets trolled by hand axes so no), but certainly not DS -> DS+ (maybe in actual gameplay, but this isn't that), but lol to considering that, she wants +Skl/-whatever in nearly no other matches, anyways Swordbreaker and Corrin getting 2HKO'd means it's dragonstones or bust which... yeah likely not off of that accuracy, except hmm, Camilla doesn't double so I don't think she can manage the effective 3HKO swinging into DS+ so... except Corrin has to land the second hit then since with -luck she doesn't 2HKO at base, which probably doesn't happen so Camilla gets a third swing and--wait why wouldn't Camilla just throw hand axes here, she loses like nothing here by doing so except a bit of non-Savage Blow damage, it's not like Corrin can afford a turn not using dragonstones, yeah this probably works regardless.
Corrin vs. Leo - Needs to dodge either the second of third shot of Nos but she can probably do this.
Corrin vs. Elise - There's going to be a bit of a theme here.
Ryoma vs.
Hinoka - WTA says hi
Ryoma vs. Takumi - WTA says hi again
Ryoma vs. Sakura - ORKO
Ryoma vs. Xander - Trying to match counter for counter here is a lost cause, so Xander wants a lance here, this makes Ryoma 8HKO (so, four-round) but his counters absolutely miserable, oh boy something to the tune of a 15HKO, you sticklers for subtractive defense better not see that as mattering since lobsterman looks even worse there, at least crits/astra speed this up which is good because Xander 3HKOs him otherwise, but yeah that's probably enough since Xander will probably whiff at least one attack in the meanwhile.
Ryoma vs.
Camilla - Swordbreaker
Ryoma vs. Leo - If Corrin could do it, imagine how much easier it is for lobsterman here
Ryoma vs. Elise - it's okay elise you're still cool
Hinoka vs.
TakumiHinoka vs. Sakura
Hinoka vs.
Xander - Trade out sword for axe, seriously Hinoka Bolt Naginata hits after WTD scares nothing. I guess if I was sticking to subtractive defense harder this would tilt, but eh, more inclined to be harsh towards bad offense than (mostly) academically bad defense.
Hinoka vs.
Camilla - It's hard to argue with an axe to the face
Hinoka vs. Leo
Hinoka vs. Elise
Takumi vs.
Sakura - wait im dumb
Takumi vs.
XanderTakumi vs.
Camilla - Strictly speaking Silver Yumi doesn't quite rise to the level of OHKO here.
Takumi vs.
Leo - Bowbreaker is kind of hilariously irrelevent since the shitbrat has to deal with WTD anyways.
Takumi vs. Elise - Except that doesn't matter here unfortunately
Sakura vs. Xander - Xander vs. mage
Sakura vs.
Camilla - uh Camilla just goes first and onerounds her with a lance
Sakura vs.
LeoSakura vs.
EliseXander vs. Camilla - Again Xander wants an axe so he can actually hit with a degree of reliability here but Savage Blow is still a thing and Bolt Axe is doing actual damage if he does, he could try for swording to stave that off but then that just gets met by lances putting his hit rate in the shitter. Granted Trample isn't a thing here (which I forgot to account for, oops im dumb) so Xander might pull this off regardless? Yeah thinking on it some more he probably can.
Xander vs.
Leo - Oh lord.
Xander vs. Elise -
Camilla vs. Leo - Again, lances.
Camilla vs. Elise
Leo vs. Elise - Leo something like 3HKOs, Elise won't even three-round in practice
