The PHB2 class Duskblade seems appropriately elven.

The 2E typical elf warlord was ftr/wiz, which we don't have anymore.

Does duskblade capture the essence of the Cerilian Elf magic?

I'm thinking it doesn't, because of its lack of higher level wizard spellcasting.

I suspect elf ftr/wizard types are prestige classes

Like
Elf Paragon 3, Wizard (Elf generalist) 6, Abjurant Champion 3 (giving bab +8 and caster level 11 at level 12)
or
Fighter 2, Wizard 4, spellsword 1, Abjurant Champion 5 (giving bab +10 and caster level 10 at 12th level)

It seems like it shouldn't be all open and the DM makes each elf randomly.

Fighter/Wizard conversions from 2E for cerilian elves ought to have a prestige class selected for the campaign to represent them.

Bladesinger maybe works better then the others (but as an optimizer, UGH, bladesinger is a crappy prc)
