Also, most URs aren't cost-effective for us non-paying players (not sure if you are one or not). It's much easier to buy elite rares and junk URs and build a strong deck using that. For example, if you're Forest, get a PM Adva (great skill, meh stats but you only want him for the skill anyways). If you're Water, get a PM Nergal (same reason as Adva). Fill your frontline with cheap URs or elite rares that grant great skills. Don't worry too much about attack stats. Fill up your backline with super cheap rares with good stats like Ammit (PM one has 8000+ attack).
