Only because you asked
I would humbly submit my own list for giving a typical dark elf list a good run for their money. Dark Elves really are one of the tougher matchups for High Elves no matter how you swing it though.
Archmage, Level 4, Forliath's Robes, Guardian Phoenix, Jewel of the Dusk (Lore of Light)
Mage, Level 2, Seerstaff (Pha's, Banishment)
Mage, Ring of Corin, Gem of Courage (Lore of Light)
Mage, Anullian Crystal (Lore of Light)
35 x Spearmen, Full Command
14 x Archers, Musician
11 x Archers, Musician
14 x Swordmasters, Standard, Standard of Balance
14 x Swordmasters, Standard, Gleaming Pennant
17 x White Lions, Full Command, Banner of Sorcery, Dragonhorn
5 x Dragon Princes
2 x Great Eagles
D3 + 1 power dice per phase, with 4 attempts to channel can rival even a Dark Elf magic phase with the dagger. 2 x S7 banishments to deal with shades quickly and Shem's for Hydras poses a significant ranged threat to all aspects of a dark elf army, and the Ring of Corin lets me deal with the Pendant. Pha's protection drops the X-Bowmen down to 6's to hit. Speed of Light gets me my rerolls back vs. I6 Dark Elf elites. Net is also particularly useful as magic defense; most sorceresses sit in a S3 bunker, elminating their casting ability 50% of the time. All of these spells are on 3 power dice or less.
Swordmasters with the Standard of Balance would be hell for Witch Elves - poor things would lose both hatred and frenzy.
Regardless of how the game goes, though, a match versus Dark Elves is always downright mess. Getting the first turn really helps, but I'm going to be 6" back from the line versus dark elves, forcing them to come to me with my long range nukes.
