That is a solid and redundant list. Moreover, I believe it plays well in all phases of the game.
I have a lot of confidence in the Dark Elves too. I understand three units of Dark Riders might be too much though. Two would be sufficient. Here's an alternative that functions the exact same way and is even more shooty (91 rxbs).

First of all: Purple sun makes Cauldrons disappear
And? There's a spell to make anything disappear in the game. The Death Hag has a brilliant ward save against assassination spells and they are too tough to crack for most hunter units. She is more survivable than a
BSB Master while providing the troops with valuable buffs. Enemy wizards are naturally the number one target for my Lore of Death Supreme Sorceress.
