Alright there is some genuine interest in this! Very good! So let me elaborate on this a bit. I was new also last year on the Eurobash (organized by the Warhammer-Empire forum) so take this with a grain of salt
First negative on a Lizardmen warband is the amount of Hero's these are your money makers between games so you need literally all of them and hope some henchmen will ascent soon. So starting with 500 gold
First you will need a Skink Priest he is your leader (-60 gold)
-- Second down fall, IF your priest dies you NEED to re-buy him and play 1 game without a leader.. (wait WUT!), so what ever you do DON'T let him need to roll on the injury table.
So next you can have one Saurus Totem Warrior he is your pinch hitter (-60 gold)
Then 2 Skink Great Crests as your last 2 hero's you can start with (2x 30=60 gold)
So there you have it.. 3 characters that are actually pretty squishy and one hitter.. no biggy right we will just fill out with hitting henchmen.
Well here we go again..
Special rule: Saurus Rarity: Can never include more Saurus Braves then there are Skink Braves. and there is a cap of 4 on the Saurus Braves as well
So you might want 4 Saurus Braves (40 gold per one) but then you NEED atleast 4 Skink Braves as well (20 gold per one)
Hero's 500-180= 320 left.
4 Saurus = 160 + 4 Skink = 80 leaving 80 gold to some other thing with (gear which will cost you also, so no option to really go full out yet)
Or should you go for the really hard hitting Kroxigor of which you can have 1 of. Well take out your purse then.. that's a -200 gold leaving 120 to buy a Saurus and a Skink leaving about 60 gold for gear.. that is a very small warband there. and losing that Kroxigor will hurt you and he is LARGE so he can be picked out by shooters and as a Henchmen has a bigger chance to DIE on the Injury table.
So taking all this into account I came up with a warband tactic of harassment. Using your big amount of shooting (skinks are low cost and average shooters but you can field lots) and using your power hitters as a sort of body guard. So my gear would also need to be looked at that way, so lots of bows.
Start list (not yet knowing how important it was to start with full hero load):
Skink Priest - Bone Helmet, Shield, Sword, Short Bow (90)
Saurus Totem Warrior - Axe, Shield (70)
Skink Great Crest - Axe, Shield (40)
3 Skink Braves (group1) with Short Bows (75)
3 Saurus Braves (group 2) Axe and Shield (150)
3 Skink Braves (group3) Short Bows (75)
=500
List I ended up with after 5 games and a free for all (4 player) having som luck in getting light armour (you also pay top price for that but luckily you have scaly skin and with cheap shields gives you a decent save):
Skink Priest - Dagger, Short Bow, Bone Helmet, Shield
Saurus Totem Warrior - Spear, Light armour, shield
Skink Great Crest - Axe, Short Bow, Shield
Skink Great Crest - Spear, Short Bow, Shield
Skink Brave (ascended) - Dagger, Short Bow, Shield
Saurus Brave (ascended) - Axe, Light Armour, Shield
Henchmen group1: 1 Skink Braves - Dagger, Short Bow
Henchmen group2: 1 Saurus Braves - Axe, Shield
Henchmen group3: 3 Skink Braves - no equipment (Daggers)
After my experience I made this new list though it has been a while since I looked at this and just skimming this I'm not sure if this is good. As Mark of the Old Ones can only be bought at making your warband..(change a failed dice roll in a successful one once per battle) I took this one for sacrificing some bodies.
Skink Priest - Mark of the Old One, Short Bow, Shield (120)
Saurus Totem Warrior - Mark of the Old One, Spear, Shield (125)
Skink Great Crest - Short Bow (35)
Skink Great Crest - Short Bow (35)
2 Saurus Braves - Spear Shield (110)
3 Skink Braves - Short Bow (75)
=500
Most equipment that is auxiliary like melee weapons on your Crests can be bought pretty soon anyway so keep it cheap and just for initial protection. Also count on losses for your skink braves with WS2, T2 and W1 in combat they go down fast!
I would like to have a Kroxigor but on his own he would be a gold sink.. so just need to keep hoping on a jackpot somehow to buy him later when you don't have to replace much of your skink braves.
