While a deck of cards has 52 individual, unique cards, there are only 20 individual amino acids used by living things. And it's unclear as to whether or not the "minimal organism" requires all 20; I think it's been estimated that an organism could carry out all the metabolic processes of life using a subset of only (I think) 12 different amino acids.
