Been working on this theme for a while, brainstorming ideas on how this can work.

I came up with a list of the following 25 requirements. Let me know if this sounds interesting, confusing, etc. Constructive criticism welcome!

A couple of notes:

A) Topps League Leader cards featured 3 different players so you would use all 3 players featured on whatever card you select.
B) The way baseball cards work is they are always a year behind. For example, 1987 Topps are for the 1986 season.
C) All rookie cards can be twisted to any season of that player's career.
D) Traded/Update cards must use a season from the player's new team.
E) All other cards must be from the year you select. So if you select 1986 Dwight Gooden Diamond King, you would use his 1985 season, capiche?
