Ok for the army.. well ive never played lizardmen, ive played against them a few times but they are much too .. well.. weird for me. The BEST way to start an army, is to buy an army book, read the WHOLE thing, if you dont understand some of it ask people. then once you have an idea what you like the look of, buy a hero model, paint him, give him a cool name, dont spend too many points on him, and then buy some basic troops as support, ive been told that 2 boxes of skinks and a box of saurus warriors is a good start. make sure to use some contrasting colors aswell, the last thing you wanto do is finish a unit and then realize the color scheme looks horrible!! and trust me, ive done that.. not a good place to start
