One of my many threads in a series created for each color for those with color-specific breeding goals who want a quick reference sheet. This list will be updated with any new additions to the game (Bases, apps, etc) Some submissions are subjective to what I think should be included. Feel free to comment any suggestions to be added/corrected. (To find the master list click here)
