The credits for this new baseball cards set go to our forum users bigrod and fhomess. Thank you, guys! Thanks to DCHepler25 for the hof-single-plaque and hof-double-plaque cards.

Templates can be appended with a secific year or decade, at which point that card will be used. So for All-Stars, if you have the following files:
all_star.xml
all_star_2015.xml
all_star_2010-2020.xml

In 2015, the _2015 card will be used. For all other years in the "2010s", the _2010-2020 file will be used. For all other years, the base card will be used.
