Quick update - I finally got around to testing my list (or a very similar version of it anyways) against my mate's lizards who had (roughly) the following:
Slaan lvl 4
Skink priest lvl 2
Oldblood
30 Temple Guard (slaan here)
30 saurus warriors (oldblood here)
2 units of 30 skinks with blowpipes (priest in one of these)
Ancient steg with giant blowpipe things
and a Bastiliadon.
Long story short i managed to win more or less even after the white lions...and the lightweaver...AND the noble BSB got themselves magiced to death because I forgot to dispel a remains in play spell. The light coven was fun (even completely shutting down the slaan's magic phase one turn due to net of Amyntok!) but it was difficult to get lots of spells off, especially after I lost my lvl 4, so I think some buffs like the book of hoeth and miscast defence might be an idea too... changes to make I think include the Banner of the World Dragon, and maybe swapping the weaver for an archmage with the book of hoeth...
The dragon...I'm not sure on... it was good, pulverising the ancient steg...but other than that it was a great big distraction, having things chase it, turn to face it etc, and there were no war machines to kill it this time around... I'll probably play it a few more times but I think it might be shelved in the long run. The alternative list I had (which was changed from the above) included a loremaster of hoeth (who would know every spell as far as I know) as well as 2 units of archers and 2 bolt throwers...more defensive but certainly more fire power.
Thanks for the help!
EDIT: I've gone and done a re-think of the dragon & light coven list (having decided to separate them now), may I ask what you think of the dragon list?
Spellweaver - lvl 4 (uses high magic) - 220
Noble - BSB, Enchanted Shield, Heavy Armour - 104
Dreadlord - Heavy Armour, SDC, Great Weapon, Talisman of Pres., Ironcurse Icon, Black Dragon 510
20 Bleakswords - Banner - 190
20 Spearmen - Banner - 190
5 Dark Riders - Crossbows, Shields, Musician - 110
5 Dark Riders - as above - 110
5 Ellyrian Reavers - Bows, Spears, Musician - 105
12 Deepwood Scouts - Hagbane, Musician - 202
15 Swordmasters - Banner - 205
30 White Lions - Banner of the World Dragon - 450 (Noble & Weaver here)
2 Great Eagles - 100
Total 2496
- aim of the game here, seeing as I like to make things all comers is target saturation to allow the dragon to arrive unscathed. The plan is for warmachines, missile troops and the like to shoot at the scouts and cavalry who are going to be very close to them first before they turn their attention to the dragon, by which point (hopefully) they won't be able to kill it and it'll be on them. Eagles can also function like this or go as a kind of screen for the dragon (i'll experiment on that one to see which is best) to stop it from being shot/charged prematurely.
The Lions are my main killy unit, and I plan to use the weaver to cast (among other things) walk between worlds to make them ethereal and move even faster as well as regain wounds via the wood elf high magic lore attribute (1 successful cast = 1 token, 1 token = 1 unsaved wound can be ignored, and this can be stacked for multiple saves), which should make the lions very difficult to kill via magic with their 2+ ward and this thing as well.
Swordmasters will be a flanker unit, and will probably march up behind the spearmen/bleakswords so they don't get shot to bits, whilst the spearmen themselves hold down a unit for the swordmasters to finish off.
Dragon is a monster/warmachine/character hunter, as well as a flanker. It'll be used to help the sword-master/spearmen combat, and could also be used to take out smaller lightly armed units...
I know dragons aren't the greatest, due to the points sink, but they're good fun and awesome when they work! If the above helps the dragon list to be somewhat viable then I'm all for it! I've also been tinkering with the light council list too, but decided to make that fully defensive (above high elf and dark elf infantry + 2 units of 15 glade guard and 4 bolt throwers and 4 wizards lol), I'll probably playtest both and see how they do.
