In the late 1980s, Don was one of the playtesters from the University of Pennsylvania that Richard Garfield tagged to help get the Alpha card set (and game rules) ready for public consumption. Together with Bill Rose, Joel Mick, Charlie Catino, Howard Kahlenberg and Elliott Segal, Don formed the "Penn group" that designed Mirage and Visions.
Originally, the card Feldon's Cane was named "Feldon's Ice Cone", which was an anagram for "Don Felice Cone". When the word "Ice" was removed due to the artwork mistakingly depicting a cane, the anagram no longer worked. This was remedied with Delif's Cone in Fallen Empires, which is also an anagram of Don Felice (with an added "s").
