Lizardmen are balanced...... in a higher points game. It is time for one of my bogus theorems.
The more dinosaurs your army has, the cooler, and stronger it is. Never forget that you need skinks to hold the flanks up, and to give all that fast cavalry what-for. Don't be bothered with javs, 'cuz when you have to get that close in, they will charge you, and put a miserable end to your skinks. Instead use blowpipes, and don't be afraid of 6's-every poisoned hit counts towards making your opponent taking the piss with your skinks :biggrin:
If you have the points, use chameleons. They are expensive, but look closer..... BS 4, and they can scout many a place, and make your opponent diver some of his forces to try and nail these bastards, which are hard to hit at range anyway. Like, even something with BS 4 will need 5+ to hit them.
NEVER, and I mean never, go into battle without some heavy blocks of saurus. They form the backbone of your army, and seeing as they are rough as guts, and can fight really well in combat. If you like to simply roll your saurus up, give them quetzl, to make them really hard to crack. Trust me, I've had sauruses take down a hydra. Also consider playing a sacred host to pass on some benefits to the skinks.
With magic, don't fall into the trap of getting an uberated slann. They may be good, but they can still be killed. Instead, invest your points in a carnosaur. It allows you to take down the big things that may challenge your army, and with a big man on the back like an oldblood, the whole thing just gets worse.
Skink priests are great. If you want to make them fast as well as good, give them the cloak of feathers, and fly around zapping things. You will need a few of them to swarm the enemy's magic phase, and for around 100 pts, they are cheap as chips. Keep in mind that they are lvl 2.
Finally, never go anywhere without a trusty stegadon. Period. They have a bolt thrower which seems innacurate, but actually kicks ass. And when the bloody thing gets into combat, watch your opponents face turn white as you wreak absolute havoc on them with D6 Str Impact hits, in addition to another 4 attacks..... and the skinks on the howdah get to attack.
Specialist units are also good, but pay special attention to the Cav. You need them to crack some of the skirmishers who will typically move out of the way of your normal units. Even though they are expensive, they are frighteningly good at smashing the crap out of ranged units, and getting in there to do it...... Plus, WS 4!
So, there you go
