We have a total of four people interested. As for the different Digimon, I think I may have a way. Every Digimon has a Type. Unlike Pokémon, Type in Digimon doesn't play too big a role in strengths and weaknesses (that role is Attribute) of a Digimon. That being said, have a list of types in the Digimon series. Rookies must be more distinct, but as lines progress, I will allow overlapping, especially at Mega level (ie- two Holy Knight type Digimon).
