Ty but i want to get to go on 300 points in order to play anything recomeded but exept bastalion for those 300 points xD?
My suggestion:
pick a box of skinks: it's 20 Euro and contains 24 skinks.
10 of them can be used as regular skinks (80 pts)
10 of them can be converted into 2 units of 5 x chama skinks (120 pts each)
The Alpha skink could be converted into a Skink Chief (it's 80 pts): it won't serve you too much, cause it's useful only as general for a skink army... but that would work for the future.
So, with a really minimal expense you'll have 320 points of useful units (10 skinks are fast and can take objectives or act as disposable screen to avoid charges on your precious carnosaur) .
With what you've already got (from the starter box), you have suddenly a 1020 pts army.
is that too much, and you would like to have exactly 1000?
Because you could buy a salamander (60 pts) and use it instead of the skinks.
Speaking about salamanders, you can do something else.
Remember that the skink box contains 24 of them?
you use 10 as skinks, 10 as chama skinks, 1 as skink chief... the last 3 can be assembled with javelin and used as handlers. At this point you just need to find something to use as salamander (a single khorne flesh hound is perfect, on ebay you'll find it at a lower price than regular sallies).
