These targets add up to 108 because a card can fill more than one role. 4 of your cards count in multiple rows. Modal spell/land cards count as whole lands here; the card-type sections use the front face. Your commander is excluded from these counts.

Roles use imported classifications or curated sample labels. 0 cards lack role data, so counts may be incomplete. Plan counts the cards that fill none of the rows above: the ones this commander’s decks play most distinctively, taken best first once the role targets are met.
