Good themes. The 100M theme is particularly challenging.
One suggestion: for the Bingo Card themes, you might want to make it a rule that teams include which Bingo Card number they are using in their team names. This will help with roster verification.
One question: for the 110M "Two Clones" theme, can the teammates of the two chosen clones be clones themselves? Lets say Chipper Jones is your hitter clone, can you roster several versions of Greg Maddux as long as they were teammates in the rostered years?
