well, if you plan on being competitive the island of blood wont be your best bet as youll only be using the swordmasters, lothern sea guard and mage, altho the rule book is a good idea if you dont have one or easy access to one. your main show should be provided by units in your elite slot so phoenix guard, whitelions, swordmasters and maybe one or two chariots are what you should be getting, along with enough sea guard to make up your required core points allotment
