Considering a speed run

[Mekkah]

Please do not bother with Azel/Lachesis, that definitely is not going to cut it. Magic Sword spamming Delmud/Nanna are grossly overrated, there's simply not a big enough Def/Res gap to override the huge power difference coming from both their Str/Mag gaps (both in caps and stats itself) and the higher power of the weapons they can wield physically (Silver Blade has 20 Mt, for example).

Plus, those magic swords are desired by more people (Odo kids, Patty, Fee), and not all of them are good. Wind Sword and Thunder Sword are the only decent ones, given their 2 and 7 Wt at range respectively. Fire Sword at range weighs you down by 12 (as much as any lance, or Hero Axe), and Earth Sword by about as much, plus Earth Sword is costly and has only 10 uses. If Delmud and Nanna rely on those things to do damage, that cripples the 1-2 range options for some others, and that cannot be a good thing.

I've watched that Nicovideo run up to near the end of chapter 2. A bit suboptimal in places (EXP department for Lachesis and Diadora...also contender for worst use of Sylvia*) and some questionable item choices but its pretty good. Though I think some of the more bizzare things were luck manipulation of some kind or other

Trwaling my hard drive it seems I have 3 FE4 runs on there. I can confirm 2 of them are AAAA. One of them was less than 300 turns (it doesn't bother to pair Sylvia), one is 335 turns (pairs everyone), one I can't confirm (all subs). I don't know if to post them as it'll be mimicing their choices as opposed to making your own what can I say it was by mimicing the snippets of the all subs that worked that I leanred how to play FE4

The one I can't confirm may not even be AAAA and I can't confirm it due to not knowing what emulator it was recorded on stupid emulator movies only playing in sync on the version of the emulator they were created on and usually nobody noting what version that was

I remember one of the runs did Azel-Edin for first gen rescue staff (A bit overkill as you don't need it that badly for gen 1 though for gen 2 making good use of it in chapter 10 and final is fairly imperitive) but other than that the pairings were pretty regular stuff, you-know Levin-Tiltyu, Claude-Fury, Lachesis-Beowolf...

Random note: I just found my first completed FE4 playthrough was 397 turns...talk about cutting it thin...I didn't get an A rank due to defeats though

If it's only important for Ch 10 and Final, then you don't have much of a benefit in getting it in Gen 1, Rescue would otherwise be purchased from the Ch 10 shop.

I guess he wants the Rescue Staff so that he can use the Rescue Staff glitch, it'll save some turns.

Personally I'd count the Rescue glitch as cheating, I doubt he'd want it for that. It's more that it's the closest thing to a Warp staff that doesn't bring you to a castle, which allows you to make some units move a whole bunch of spaces in their turn. Helps stragglers like Tinny to keep up with the rest, I guess.
