first download the codex (experimental)...i don't have the exact link...but i'm sure its floating around EO somewhere...then you should post some army lists here at EO....just in case you are wondering you CAN still buy harlequin models from the GW archive online...they are 2ed models, but still very cool..remember...wh en painting harlequins, you can feel free to do anything you want, but generally they are painted in really bright colors...make sure you spend a good deal of time painting them cause really you don't have all that many models to do..
