I like many of the set styles we're seeing, though I have to ask if it's time we decided on a consistent format for D&D power cards in MSE? If we could come up with a suggested set of fields, then card sets and templates could be compatible, making it simpler for users to mix 'n' match for different player preferences.
I haven't tried making a set from scratch myself, but one thing I have noticed is that the fields for class, level and power type etc. don't match up between templates, and they're often combined rather than separate (i.e. "Wizard Attack 1" shows up as a single field, rather than there being separate fields for Class, power type and level). Would it be a good idea to have separate columns for those things, which are then combined in the template? It would make sorting and filtering sets easier, too.
