List 2 is looking good, proper anvil with the Naiad horde. If the Queen is staying in the list, I’d recommend swapping her icy breath (which she will rarely use) for that chunky surge (8), then dropping the Tome from the Skald. As I always try to give my army standards something to do, you could toss Lute or Boomstick or Zephyr Crown (!) onto the Skald instead. I’d also love a snow fox for the Frostlord, rev up that blender!
EDIT: Also folks will recommend the Hammer for the Naiad horde, and given that you know your opponents (AD + Undead having a lot of Def5+), it’s probably a good choice. If you do take Lute on the Skald, I’d suggest passing on the Hammer, as you can do better than 4+ thanks to hills and bane chant … however I’d probably favor the Boomstick myself for chaff clearing, etc.
EDIT2: Me again, with another thought. If you really want to chip some teeth, the list has the points to swap the Queen over to a Thegn on Frostfang w/ Inspiring Talisman, give the Hammer to the Naiads, and leave the Skald w/ Tome of Darkness. Frosthegn are stupid good, and can fill a variety of roles, from babysitting early game, to ranging down a flank, to rampaging into a flank, to glowering in a quarter / on a point to claim it, to just breaking faces. It’s less grind-oriented than the Queen’s Heal (5), but certainly punchier.
