shouldn't you be playing brettonians? Just kidding

I would make a few suggestions though.

Get musicians on all your units. Drop the big knight blocks down to six wide (maybe 5 wide if you're putting characters in), you'll never get that rank bonus. Get the warbanner on one of your big knight units. Warpriest can't take a dispel scroll, so get them a magic weapons (sword of might or something like that)

Bsb needs a horse

Maybe get some outriders for shooting and a wizard for scrolls if you think you need them. I would be scared to meet a magic heavy army with lore of beasts or metal.

 

Against undead this list will last about three turns max, four if the oppenent purposefully plays like an idiot. The one way to win against undead is combat res....and you have none to begin with.

Big units of knights are unwieldy, and he'll just Dance into your flank with a cheap unit then bog you down at his convenience. Also you have almost no magic offense or dirty tricks to play, and the magic items are enough to hurt him, but not enough to win combat or kill his main characters. Laurels of victory is always good against undead.

If he wrote you that list, i think he just wants to win an easy one over you.
