Odd Ones Out simply limit the use of cards to ones with odd mana value (only monster cards and does not include summoner cards). There doesn't seemed to be much difference between odd cards with even cards. You could clearly see in the figure below that both cluster have very similar number and composition. In my opinion there seemed to be more number of odd mana cards compared to the others. But particularly odd mana cards does have more number of ranged cards, which clearly shown in the 5 mana and 7 mana groups, compared to the rest.
