Matchup Analysis (anticipated problems and solutions).
WOC
Concerns: Lots of small fast Units/Characters with good statlines (Daemon Prince, Special Characters (Throgg), Disklords, Chimera, Chariots, Trolls and Skullcrushers). Will get points by engaging in CC or using Death Magic.
Counters: BoTWD, Lots of High S attacks, OTS, Flaming Attacks, Book, Scroll.
DOC
Concerns: Wall of Nurgle, Beasts of Nurgle, Skillcannons.
Counters: BoTWD, Flaming Attacks, OTS.
Skaven
Concerns: Dread 13th, Wither (very bad for Teclis), Slaves, Bell, Plague Furnace, Hell Pit Abomination, Doomwheel, Warp Lightning Cannon, Engineer Toys.
Counters: High Volume of Hits, no units on foot, Flaming Attacks, BoTWD, high S attacks, Book, Scroll.
Ogres
Concerns: Gutstar, Mournfangs, Ironblaster, Redirectors, Maneaters (Pistols and Poison), Leadbelchers.
Counters: High S attacks, Multiple Wounds, OTS (for Gutstar), Speed, Flaming Attacks (Trollguts).

Dark Elves
Concerns: Hellbrone, Shadow Magic, Witch Elves with buffs, Executioners, Peg Characters, Warlocks, Dark Riders, RBTs.
Counters: Magic Missiles, BoTWD (for Hellbrone), Frosthearts, lots of attacks (to kill Witch Elves as quickly as possible and to do max damage to executioners before they strike), Armour, Scroll, Book, High S attacks (to kill Peg Characters), OTS.

Archmage (320pts): Elven Steed, Level 4, Lore of Beasts, Book of Hoeth, Khaine's Ring of Fury.

Noble (172pts): Heavy Armour, Lance, Shield, BSB, Banner of the World Dragon, Elven Steed with Barding.
Noble (112pts): Heavy Armour, Lance, Shield, Elven Steed with Barding, (BRB) The Other Trickster's Shard.
Noble (95pts): Elven Steed, Heavy Armour, Lance, Enchanted Shield.
Core (509pts):
5 Ellyrian Reavers (85pts): Bows.
5 Ellyrian Reavers (95pts): Bows, Musician.
13 Silver Helms (329pts): FC, Shields.
Special (204pts):
6 Dragon Princes of Caledor (204pts): Musician, Standard Bearer, Banner of Eternal Flame.
Rare (465pts):
Flamespyre Phoenix (225pts).
Frostheart Phoenix (240pts).
Which really isn't very different from the list you posted above. Which I proceeded to critique for being one dimensional
.
The idea with the list above is to pile all the characters into the Dragon Princes or Silver Helms, depending on the tactical situation. If you see Trolls or Wall of Nurgle, you put them all in the Dragon Princes for flaming attacks. Otherwise, they go in the Silver Helms (who have more bodies). Then get into combat and apply dual Wildform, Savage Beast and Pelt.
On the Charge under Boasted Savage Beast, there really isn't anything the Nobles can't kill. They flat out ignore armour (and Regen if in the Dragon Princes), have ASF rerolls against I7 or less, force ward save rerolls and wound just about anything on a 2+. A Steam Tank takes an average of 13 wounds (18 attacks, 16 hits, 13.333 wounds). Similar things will happen to a unit of Skullcrushers, Mounfangs or Demis and that doesn't even consider the effect of the Silver Helms or Dragon Princes.
The Bus is less likely to die to Dwellers or be neutered by Acquiescence, Cacophonic Choir or Ash Storm because you have a Scroll, Level 4 with the Book and the ability to cast Savage Beast or Wildform to increase your S.
The List has Soul Quench and the possibility of Curse or Amber Spear for a ranged presence and to draw the enemy scroll. Wake of Flame from the Flamespyre can kill redirectors and wear down Steadfast blocks of things like Skaven Slaves.
Please note that the list above is a draft and is due for some severe change. The scroll is probably going to the Lv4 so that the Lv2 can be dropped for better defensive kit on the nobles.
This is already a really long post (for me anyway) and I've written all I'm going to tonight. I'll add to it/answer questions tomorrow.
