- Card Primitives system. Check Royal Assassin in RV, 10E, M10
- Please review, is sets/primitives a good directory? Should we rename MTGCard into "CardPrint"? 
- Unfortunately for now it is not possible to "override" a Primitive. A card that links to a primitive but also defines new "values" will create its own data and ignore the data in the "linked" primitive for the time being. I hope to solve that at some point...
