Stardeck Cribbage

5 of a kind scores 20: ( 2*5!/2!(5-2)! .

Five 5s scores 40: 2*( 5!/2!(5-2)! + 5!/3!(5-3)! ).

Super Hands (one card from each suit) adds 5 points (one point per card which is the same as a Flush).

This, by the way, would add 5 points to five-of-a-kind, so the top score would be 45 with Super Five-of-a-kind of 5s.
